Create a custom design using the TPS62130A-Q1
with the WEBENCH® Power Designer
With a wide operating input-voltage range of 3 to 17
V, the devices are ideally suited for systems powered
from intermediate bus power rails. The devices
support up to 3-A continuous output current at output
voltages between 0.9 V and 6 V (with 100% duty
cycle mode). The output-voltage startup ramp is
controlled by the soft-start pin, which allows operation
as either a standalone power supply or in tracking
configurations. Power sequencing is also possible by
configuring the enable and open-drain power-good
pins.
In power save mode, the devices show quiescent
current of about 17 μA from VIN. Power save mode
which is entered automatically and seamlessly if the
load is small, maintains high efficiency over the entire
load range. In shutdown mode, the devices are
turned off and shutdown current consumption is less
than 2 μA. The devices are packaged in a 16-pin
VQFN package measuring 3 × 3 mm (RGT).

9 Detailed Description
9.1 Overview
The TPS6213xA-Q1 synchronous switched mode power converters are based on DCS-Control™ (Direct Control
with Seamless Transition into Power Save Mode), an advanced regulation topology, that combines the
advantages of hysteretic, voltage mode, and current mode control including an AC loop directly associated to the
output voltage. This control loop takes information about output voltage changes and feeds it directly to a fast
comparator stage. It sets the switching frequency, which is constant for steady state operating conditions, and
provides immediate response to dynamic load changes. To get accurate DC load regulation, a voltage feedback
loop is used. The internally compensated regulation network achieves fast and stable operation with small
external components and low ESR capacitors.
The DCS-Control topology supports PWM (Pulse Width Modulation) mode for medium and heavy load conditions
and a Power Save Mode at light loads. During PWM, it operates at its nominal switching frequency in continuous
conduction mode. This frequency is typically about 2.5 MHz or 1.25 MHz with a controlled frequency variation,
depending on the input voltage. If the load current decreases, the converter enters Power Save Mode to sustain
high efficiency down to very light loads. In Power Save Mode, the switching frequency decreases linearly with the
load current. Since DCS-Control supports both operation modes within one single building block, the transition
from PWM to Power Save Mode is seamless without effects on the output voltage.

9.3 Feature Description
9.3.1 Pulse Width Modulation (PWM) Operation
The TPS6213xA-Q1 operates with pulse width modulation in continuous conduction mode (CCM) with a nominal
switching frequency of 2.5 MHz or 1.25 MHz, selectable with the FSW pin. The frequency variation in PWM is
controlled and depends on VIN, VOUT, and the inductance. The device operates in PWM mode as long the output
current is higher than half the ripple current of the inductor. To maintain high efficiency at light loads, the device
enters Power Save Mode at the boundary to discontinuous conduction mode (DCM). PSM operation occurs if the
output current becomes smaller than half the ripple current of the inductor.
9.3.2 Power Save Mode Operation
The built-in Power Save Mode of the TPS6213xA-Q1 is entered seamlessly, if the load current decreases. This
secures a high efficiency in light load operation. The device remains in Power Save Mode as long as the inductor
current is discontinuous.
In Power Save Mode, the switching frequency decreases linearly with the load current maintaining high
efficiency. The transition into and out of Power Save Mode happens within the entire regulation scheme and is
seamless in both directions.

TPS6213xA-Q1 includes a fixed on-time circuitry. This on-time, in steady-state operation with FSW=Low, can be
estimated as:
space
t ON =
VOUT
× 400ns
V IN
(1)
For very small output voltages, an absolute minimum on-time of about 80 ns is kept to limit switching losses. The
operating frequency is thereby reduced from its nominal value, keeping efficiency high. Also the off-time can
reach its minimum value at high duty cycles. The output voltage remains regulated in such case. Using tON, the
typical peak inductor current in Power Save Mode can be approximated by:
I LPSM ( peak ) =
(V IN - VOUT )
× t ON
L
(2)
When VIN decreases to typically 15% above VOUT, the TPS6213xA-Q1 does not enter Power Save Mode,
regardless of the load current. The device maintains output regulation in PWM mode.
9.3.3 100% Duty-Cycle Operation
The duty cycle of the buck converter is given by D = VOUT / VIN and increases as the input voltage comes close
to the output voltage. In this case, the device starts 100% duty cycle operation turning on the high-side switch
100% of the time. The high-side switch stays turned on as long as the output voltage is below the internal set
point. This allows the conversion of small input to output voltage differences (for example, for the longest
operation time of battery-powered applications). In 100% duty cycle mode, the low-side FET is switched off.
The minimum input voltage to maintain output voltage regulation, depending on the load current and the output
voltage level, can be calculated as:
VIN (min) = VOUT (min) + I OUT (RDS ( on ) + RL )
where
•
•
•
IOUT is the output current
RDS(on) is the RDS(on) of the high-side FET
RL is the DC resistance of the inductor used
(3)
9.3.4 Enable / Shutdown (EN)
When Enable (EN) is set High, the device starts operation. Shutdown is forced if EN is pulled Low with a
shutdown current of typically 1.5 µA. During shutdown, the internal power MOSFETs as well as the entire control
circuitry are turned off. The internal resistive divider pulls down the output voltage smoothly. The EN signal must
be set externally to High or Low. The typical threshold values are 0.65 V (rising) and 0.45 V (falling). An internal
pulldown resistor of about 400 kΩ is connected and keeps EN logic low, if Low is set initially and then the pin
gets floating. It is disconnected if the pin is set High.
Connecting the EN pin to an appropriate output signal of another power rail provides sequencing of multiple
power rails.
9.3.5 Soft Start / Tracking (SS/TR)
The internal soft-start circuitry controls the output voltage slope during start-up, avoiding excessive inrush current
and ensures a controlled output voltage rise time. It also prevents unwanted voltage drops from high-impedance
power sources or batteries. When EN is set to start device operation, the device starts switching after a delay of
about 50 µs and VOUT rises with a slope controlled by an external capacitor connected to the SS/TR pin. See
Figure 41 and Figure 42 for typical start-up operation.

Feature Description (continued)
Using a very small capacitor (or leaving SS/TR pin un-connected) provides the fastest start-up behavior. The
TPS6213xA-Q1 can start into a pre-biased output. During monotonic pre-biased start-up, both of the power
MOSFETs are not allowed to turn on until the internal ramp of the device sets an output voltage above the prebias voltage. As long as the output is below about 0.5 V, a reduced current limit of typically 1.6 A is set internally.
If the device is set to shutdown (EN = GND), undervoltage lockout, or thermal shutdown, an internal resistor pulls
the SS/TR pin down to ensure a proper low level. Returning from those states causes a new start-up sequence
as set by the SS/TR connection.
A voltage supplied to SS/TR can be used for tracking a master voltage. The output voltage follows this voltage in
both directions up and down (see Application and Implementation).
9.3.6 Current Limit And Short Circuit Protection
The TPS6213xA-Q1 is protected against heavy load and short circuit events. If a short circuit is detected (VOUT
drops below 0.5 V), the current limit is reduced to 1.6 A, typically. If the output voltage rises above 0.5 V, the
device runs in normal operation again. At heavy loads, the current limit determines the maximum output current.
If the current limit is reached, the high-side FET turns off. Avoiding shoot through current, the low-side FET
switches on to allow the inductor current to decrease. The low-side current limit is typically 3.5 A. The high-side
FET turns on again, only if the current in the low-side FET has decreased below the low-side current limit
threshold.
The output current of the device is limited by the current limit (see Electrical Characteristics). Due to internal
propagation delay, the actual current can exceed the static current limit during that time. The dynamic current
limit can be calculated as follows:
I peak ( typ ) = I LIMF +
VL
× t PD
L
where
•
•
•
•
ILIMF is the static current limit, specified in the Electrical Characteristics
L is the inductor value
VL is the voltage across the inductor (VIN - VOUT)
tPD is the internal propagation delay
(4)
The current limit can exceed static values, especially if the input voltage is high and very small inductances are
used. The dynamic high-side switch peak current can be calculated as follows:
I peak (typ ) = I LIMF +
(VIN - VOUT )× 30ns
L
(5)
9.3.7 Power Good (PG)
The TPS6213xA-Q1 has a built-in power good (PG) function to indicate whether the output voltage has reached
its appropriate level or not. The PG signal can be used for start-up sequencing of multiple rails. The PG pin is an
open-drain output that requires a pullup resistor (to any voltage below 7 V). It can sink 2 mA of current and
maintain its specified logic low level. TPS6213xA-Q1 features PG = Low when the device is turned off due to EN,
UVLO, or thermal shutdown and can be used to actively discharge VOUT (see Figure 46). VIN must remain
present for the PG pin to stay Low. If unused, the PG pin can be left floating.

9.3.8 Pin-Selectable Output Voltage (DEF)
The output voltage of the TPS6213xA-Q1 can be increased by 5% above the nominal voltage by setting the DEF
pin to High (1)When DEF is Low, the device regulates to the nominal output voltage. Increasing the nominal
voltage allows adapting the power supply voltage to the variations of the application hardware. More detailed
information on voltage margining using TPS6213xA-Q1 can be found in the Voltage Margining Using the
TPS62130 Application Report. A pulldown resistor of about 400 kΩ is internally connected to the pin to ensure a
proper logic level if the pin is high impedance or floating after initially set to Low. The resistor is disconnected if
the pin is set High.
9.3.9 Frequency Selection (FSW)
To get high power density with very small solution size, a high switching frequency allows the use of small
external components for the output filter. However, switching losses increase with the switching frequency. If
efficiency is the key parameter, more than solution size, the switching frequency can be set to half (1.25 MHz
typ.) by pulling FSW to High. Running with lower frequency, a higher efficiency and a higher output voltage ripple
is achieved. Pull FSW to Low for high frequency operation (2.5 MHz typ.). To get low ripple and full output
current at the lower switching frequency, it is recommended to use an inductor of at least 2.2 µH. The switching
frequency can be changed during operation, if needed. A pulldown resistor of about 400 kΩ is internally
connected to the pin, acting the same way as at the DEF Pin (see above).
9.3.10 Undervoltage Lockout (UVLO)
If the input voltage drops, the undervoltage lockout prevents misoperation of the device by switching off both the
power FETs. The undervoltage lockout threshold is set typically to 2.7 V. The device is fully operational for
voltages above the UVLO threshold and turns off if the input voltage trips the threshold. The converter starts
operation again once the input voltage exceeds the threshold by a hysteresis of typically 200 mV.
9.3.11 Thermal Shutdown
The junction temperature (TJ) of the device is monitored by an internal temperature sensor. If TJ exceeds 160°C
(typ), the device goes into thermal shutdown. Both the high-side and low-side power FETs are turned off and PG
goes Low. When TJ decreases below the hysteresis amount, the converter resumes normal operation, beginning
with soft start. To avoid unstable conditions, a hysteresis of typically 20°C is implemented on the thermal
shutdown temperature.
9.4 Device Functional Modes
9.4.1 Operation Above TJ = 125°C
The operating junction temperature of the device is specified up to 125°C. In power supplying circuits, the self
heating effect causes the junction temperature, TJ, to be even higher than the ambient temperature, TA (see
Figure 43). Depending on TA and the load current, the maximum operating TJ can be exceeded. However, the
electrical characteristics are specified up to a TJ of 125°C only. The device operates as long as thermal
shutdown threshold is not triggered.
9.4.2 Operation with VIN < 3 V
The device is functional for supply voltages below 3 V and above the UVLO threshold. Parameters can differ
from specified values. The minimum VIN value of 3 V is not violated by UVLO threshold and hysteresis variations.
9.4.3 Operation with Separate EN Control
The EN pin can be connected to VIN or be controlled separately. While the EN control voltage level can be lower
than the actual VIN value, it must not exceed VIN to avoid damage of the device. This might happen at low VIN,
during start-up, or power sequencing.
(1)
Maximum allowed voltage is 7V. Therefore it's recommended to connect it to VOUT, not VIN.

Typical Application (continued)
10.2.1.2.2 Programming The Output Voltage
The TPS6213xA-Q1 can be programmed for output voltages from 0.9 V to 6 V by using a resistive divider from
VOUT to AGND. The voltage at the FB pin is regulated to 800 mV. The value of the output voltage is set by the
selection of the resistive divider from Equation 6 (see Figure 10). It is recommended to choose resistor values
which allow a current of at least 2 µA, meaning the value of R2 should not exceed 400 kΩ. Lower resistor values
are recommended for highest accuracy and most robust design. For applications requiring lowest current
consumption, the use of fixed output voltage versions is recommended.

In case the FB pin gets opened, the device clamps the output voltage at the VOS pin internally to about 7.4 V.
10.2.1.2.3 External Component Selection
The external components have to fulfill the needs of the application, but also the stability criteria of the control
loop of the device. The TPS6213xA-Q1 is optimized to work within a range of external components. The
inductance and capacitance of the LC output filter must be considered together, creating a double pole,
responsible for the corner frequency of the converter (see Output Filter and Loop Stability). Table 3 can be used
to simplify the output filter component selection.

The TPS6213xA-Q1 can be run with an inductor as low as 1 µH. FSW should be set Low in this case. However,
for applications running with the low frequency setting (FSW = High) or with low input voltages, 2.2 µH is
recommended.
More detailed information on further LC combinations can be found in Device Behavior Under Slow VBAT RampDown and Ramp-Up Application Report.
10.2.1.2.4 Inductor Selection
The inductor selection is affected by several effects like inductor ripple current, output ripple voltage, PWM-toPSM transition point, and efficiency. In addition, the selected inductor has to be rated for appropriate saturation
current and DC resistance (DCR). Equation 7 and Equation 8 calculate the maximum inductor current under
static load conditions.

Calculating the maximum inductor current using the actual operating conditions gives the minimum saturation
current of the inductor needed. It is recommended to add a margin of about 20%. A larger inductor value is also
useful to get lower ripple current, but increases the transient response time and solution size. The following
inductors have been used with the TPS6213xA-Q1 and are recommended for use:

10.2.1.2.5 Output Capacitor
The recommended value for the output capacitor is 22 µF. The architecture of the TPS6213xA-Q1 allows the use
of tiny ceramic output capacitors with low equivalent series resistance (ESR). These capacitors provide low
output voltage ripple and are recommended. To keep its low resistance up to high frequencies and to get narrow
capacitance variation with temperature, it is recommended to use an X7R or X5R dielectric. Using a higher value
can have some advantages like smaller voltage ripple and a tighter DC output accuracy in Power Save Mode
(see the Device Behavior Under Slow VBAT Ramp-Down and Ramp-Up Application Report).
NOTE
In power save mode, the output voltage ripple depends on the output capacitance, its
ESR, and the peak inductor current. Using ceramic capacitors provides small ESR and
low ripple.
10.2.1.2.6 Input Capacitor
For most applications, 10µF is sufficient and is recommended, though a larger value reduces input current ripple
further. The input capacitor buffers the input voltage during transient events and also decouples the converter
from the supply. A low ESR multilayer ceramic capacitor is recommended for best filtering and should be placed
between PVIN and PGND as close as possible to those pins. Even though AVIN and PVIN must be supplied
from the same input source, it's required to place a capacitance of 0.1uF from AVIN to AGND, to avoid potential
noise coupling. An RC, low-pass filter from PVIN to AVIN may be used but is not required.
10.2.1.2.7 Soft-start Capacitor
A capacitance connected between SS/TR pin and AGND allows a user-programmable start-up slope of the
output voltage. A constant current source supports 2.5 µA to charge the external capacitance. The capacitor
required for a given soft-start ramp time for the output voltage is given by:

NOTE
DC Bias effect: High capacitance ceramic capacitors have a DC Bias effect, which have
a strong influence on the final effective capacitance, therefore, the right capacitor value
has to be chosen carefully. Package size and voltage rating in combination with dielectric
material are responsible for differences between the rated capacitor value and the
effective capacitance.
10.2.1.2.8 Tracking Function
If a tracking function is desired, the SS/TR pin can be used for this purpose by connecting it to an external
tracking voltage. The output voltage tracks that voltage. If the tracking voltage is between 50 mV and 1.2 V, the
FB pin tracks the SS/TR pin voltage as described in Equation 11 and shown in Figure 11.

Figure 11. Voltage Tracking Relationship
Once the SS/TR pin voltage reaches about 1.2 V, the internal voltage is clamped to the internal feedback voltage
and the device goes to normal regulation. This works for rising and falling tracking voltages with the same
behavior, as long as the input voltage is inside the recommended operating conditions. For decreasing SS/TR
pin voltage, the device does not sink current from the output, so the resulting decrease of the output voltage can
be slower than the SS/TR pin voltage if the load is light. When driving the SS/TR pin with an external voltage, do
not exceed the voltage rating of the SS/TR pin, which is VIN + 0.3 V.
If the input voltage drops into undervoltage lockout or even down to zero, the output voltage goes to zero,
independent of the tracking voltage. Figure 12 shows how to connect devices to get ratiometric and simultaneous
sequencing by using the tracking function.

Figure 12. Sequence for Ratiometric and Simultaneous Start-up
The resistive divider of R1 and R2 can be used to change the ramp rate of VOUT2 faster, slower, or the same as
VOUT1.
A sequential start-up is achieved by connecting the PG pin of VOUT1 to the EN pin of VOUT2. Ratiometric startup sequence happens if both supplies are sharing the same soft-start capacitor. Equation 10 calculates the softstart time, though the SS/TR current has to be doubled. Details about these and other tracking and sequencing
circuits are found in the Sequencing and Tracking With the TPS621-Family and TPS821-Family Application
Report.
NOTE
If the voltage at the FB pin is below its typical value of 0.8 V, the output voltage accuracy
can have a wider tolerance than specified.
10.2.1.2.9 Output Filter and Loop Stability
The devices of the TPS6213xA-Q1 family are internally compensated to be stable with L-C filter combinations
corresponding to a corner frequency to be calculated with Equation 12:
f LC =
1
2p L × C
(12)
Proven nominal values for inductance and ceramic capacitance are given in Table 3 and are recommended for
use. Different values can work, but care has to be taken on the loop stability, which is affected. More information,
including a detailed LC stability matrix, can be found in the Optimizing the TPS62130/40/50/60 Output Filter
Application Report.
The TPS6213xA-Q1 includes an internal 25-pF feedforward capacitor connected between the VOS and FB pins.
This capacitor impacts the frequency behavior and sets a pole and zero in the control loop with the resistors of
the feedback divider, per Equation 13 and Equation 14:

Though the TPS6213xA-Q1 is stable without the pole and zero being in a particular location, adjusting their
location to the specific needs of the application can provide better performance in Power Save mode and
improved transient response. An external feedforward capacitor can also be added. A more detailed discussion
on the optimization for stability versus transient response can be found in the Optimizing Transient Response of
Internally Compensated DC-DC Converters Application Report and Feedforward Capacitor to Improve Stability
and Bandwidth of TPS621/821-Family Application Report.

10.3 System Examples
10.3.1 Regulated Power LED Supply
The TPS62130A-Q1 can be used as a power supply for power LEDs. The FB pin can be easily set down to lower
values than nominal by using the SS/TR pin. With that, the voltage drop when the sense resistor is low, avoiding
excessive power loss. Since this pin provides 2.5 µA, the feedback pin voltage can be adjusted by an external
resistor per Equation 15. This drop, proportional to the LED current, is used to regulate the output voltage (anode
voltage) to a proper level to drive the LED. Both analog and PWM dimming are supported with the TPS62130AQ1. Figure 44 shows an application circuit, tested with analog dimming.

The resistor at SS/TR sets the FB voltage to a level of about 300 mV and is calculated from Equation 15.
V FB = 0.64 × 2.5mA × R SS / TR
(15)
The device now supplies a constant current, set by the resistor at the FB pin, by regulating the output voltage
accordingly. The minimum input voltage has to be rated according the forward voltage needed by the LED used.
More information is available in the Step-Down LED Driver With Dimming With the TPS621-Family and TPS821Family Application Report.

System Examples (continued)
The transfer function of the inverting power supply configuration differs from the buck mode transfer function,
incorporating a Right Half Plane Zero additionally. The loop stability has to be adapted. An output capacitance of
at least 22 µF is recommended. A detailed design example is given in the Using the TPS6215x in an Inverting
Buck-Boost Topology Application Report.
10.3.3 Active Output Discharge
The TPS6213xA-Q1 pulls the PG pin low when the device is shut down by EN, UVLO, or thermal shutdown.
Connecting PG to VOUT through a resistor can be used to discharge VOUT in those cases (see Figure 46).

11 Power Supply Recommendations
The TPS6213xA-Q1 devices are designed to operate from a 3-V to 17-V input voltage supply. To avoid
insufficient supply current due to line drop, ringing due to trace inductance at the VIN terminal, or supply peak
current limitations, additional bulk capacitance can be required. If there is ringing that is caused by the interaction
with the ceramic input capacitors, an electrolytic or tantalum type capacitor can be needed for damping.

12 Layout
12.1 Layout Guidelines
A proper layout is critical for a switched mode power supply operation, even more so for high switching
frequencies, therefore, the PCB layout of the TPS6213xA-Q1 demands careful attention to ensure operation and
to get the specified performance. A poor layout can lead to issues like poor regulation (both line and load),
stability and accuracy weaknesses, increased EMI radiation, and noise sensitivity. The layout also influences the
thermal performance of the solution by its power dissipation capabilities.
See Figure 55 for the recommended layout of the TPS62130A-Q1, which is designed for common external
ground connections, therefore, both AGND and PGND pins are directly connected to the Exposed Thermal Pad.
On the PCB, the direct common ground connection of AGND and PGND to the Exposed Thermal Pad and the
system ground (ground plane) is mandatory. Also, connect the VOS pin in the shortest way to the VOUT potential
at the output capacitor.
Provide low inductive and resistive paths for loops with high di/dt, so paths conducting the switched load current
are as short and wide as possible. Provide low capacitive paths (with respect to all other nodes) for wires with
high dv/dt, so the input and output capacitance are placed as close as possible to the IC pins and parallel wiring
over long distances and narrow traces are avoided. Loops that conduct an alternating current must outline an
area as small as possible, as this area is proportional to the energy radiated.
Sensitive nodes like FB and VOS need to be connected with short wires and not nearby high dv/dt signals, like
SW. Since they carry information about the output voltage, they must be connected as close as possible to the
actual output voltage (at the output capacitor). The capacitor on the SS/TR pin and AVIN as well as the FB
resistors, R1 and R2, must be kept close to the IC and connect directly to those pins and the AGND pin.
The Exposed Thermal Pad must be soldered to the circuit board for mechanical reliability and to achieve
appropriate power dissipation.
