TPS6100x Single- and Dual-Cell Boost Converter With Start-up Into Full Load
1 Features
3 Description
•
The TPS6100x devices are boost converters intended
for systems that are typically operated from a singleor dual-cell nickel-cadmium (NiCd), nickel-metal
hydride (NiMH), or alkaline battery. The converter
output voltage can be adjusted from 1.5 V to a
maximum of 3.3 V and provides a minimum output
current of 100 mA from a single battery cell and 250
mA from two battery cells. The converter starts up
into a full load with a supply voltage of 0.9 V and
stays in operation with supply voltages as low as 0.8
V.

Added System Security With Integrated LowBattery Comparator
Low-EMI Converter (Integrated Antiringing Switch
Across Inductor)
Micro-Size 10-Pin MSOP Package
Evaluation Modules Available
(TPS6100xEVM–156)
2 Applications
The converter is based on a fixed-frequency, currentmode pulse-width-modulation (PWM) controller that
goes into power-save mode at low load currents. The
current through the switch is limited to a maximum of
1100 mA, depending on the output voltage. The
current sense is integrated to further minimize
external component count. The converter can be
disabled to minimize battery drain when the system is
put into standby.
•
•
•
•
•
A low-EMI mode is implemented to reduce
interference and radiated electromagnetic energy that
is caused by the ringing of the inductor when the
inductor discharge-current decreases to zero. The
device is packaged in the space-saving 10-pin MSOP
package.

Line and load regulation is measured as a percentage deviation from the nominal value (i.e., as percentage deviation from the nominal
output voltage). For line regulation, x %/V stands for ±x% change of the nominal output voltage per 1-V change on the input/supply
voltage. For load regulation, y% stands for ±y% change of the nominal output voltage per the specified current change.

9 Detailed Description
9.1 Overview
The TPS6100x Non-synchronous step-up converter typically operates at a 500-kHz frequency pulse width
modulation (PWM) at moderate to heavy load currents. The converter enters Power Save mode at low load
currents to maintain a high efficiency over a wide load. Additionally, the device integrates a circuit which removes
the ringing that typically appears on the SW-node when the converter enters the discontinuous current mode.

9.3 Feature Description
9.3.1 Controller Circuit
The device is based on a current-mode control topology using a constant-frequency pulse-width modulator to
regulate the output voltage. It runs at an oscillator frequency of 500 kHz. The current sense is implemented by
measuring the voltage across the switch. The controller also limits the current through the power switch on a
pulse-by-pulse basis. Care must be taken that the inductor saturation current is higher than the current limit of
the TPS6100x. This prevents the inductor from going into saturation and therefore protects both device and
inductor. The current limit should not become active during normal operating conditions.
The TPS6100x is designed for high efficiency over a wide output current range. Even at light loads the efficiency
stays high because the controller enters a power-save mode, minimizing switching losses of the converter. In this
mode, the controller only switches if the output voltage trips below a set threshold voltage. It ramps up the output
voltage with one or several pulses, and again goes into the power-save mode once the output voltage exceeds
the threshold voltage. The controller enters the power-save mode when the output current drops to levels that
force the discontinuous current mode. It calculates a minimum duty cycle based on input and output voltage and
uses the calculation for the transition out of the power-save mode into continuous current mode.
The control loop must be externally compensated with an R/C/C network connected to the COMP pin. See the
application section for more details on the design of the compensation network.
9.3.2 Device Enable
The device is put into operation when EN is set high. During start-up of the converter the input current from the
battery is limited until the voltage on COMP reaches its operating point. The device is put into a shutdown mode
when EN is set to GND. In this mode, the regulator stops switching and all internal control circuitry including the
low-battery comparator is switched off. The output voltage drops to one diode drop below the input voltage in
shutdown.
9.3.3 Undervoltage Lockout
An undervoltage lockout function prevents the device start-up if the supply voltage on VBAT is lower than
approximately 0.7 V. This undervoltage lockout function is implemented in order to prevent the malfunctioning of
the converter. When in operation and the battery is being discharged, the device automatically enters the
shutdown mode if the voltage on VBAT drops below approximately 0.7 V.
If the EN pin is hardwired to VBAT and if the voltage at VBAT drops temporarily below the UVLO threshold voltage,
the device switches off and does not start up again automatically, even if the supply voltage rises above 0.9 V.
The device starts up again only after a signal change from low to high on EN or if the battery voltage is
completely removed.
9.3.4 Low-Battery Detector Circuit (LBI and LBO)
The low-battery detector circuit is typically used to supervise the battery voltage and to generate an error flag
when the battery voltage drops below a user-set threshold voltage. The function is active only when the device is
enabled. When the device is disabled, the LBO pin is high impedance. The LBO pin goes active low when the
voltage on the LBI pin decreases below the set threshold voltage of 500 mV ±15 mV, which is equal to the
internal reference voltage. The battery voltage, at which the detection circuit switches, can be programmed with a
resistive divider connected to the LBI pin. The resistive divider scales down the battery voltage to a voltage level
of 500 mV, which is then compared to the LBI threshold voltage. The LBI pin has a built-in hysteresis of 10 mV.
See the application section for more details about the programming of the LBI threshold.
If the low-battery detection circuit is not used, the LBI pin should be connected to GND (or to VBAT) and the LBO
pin can be left unconnected. Do not let the LBI pin float.
9.3.5 Low-EMI Switch
The device integrates a circuit which removes the ringing that typically appears on the SW-node when the
converter enters the discontinuous current mode. In this case, the current through the inductor ramps to zero and
the Schottky diode stops conducting. Due to remaining energy that is stored in parasitic components of the
diode, inductor, and switch, a ringing on the SW pin is induced. The integrated antiringing switch clamps this
voltage internally to VBAT and therefore dampens this ringing.

Feature Description (continued)
The antiringing switch is turned on by a comparator that monitors the voltage between SW and VOUT. This
voltage indicates when the diode is reverse biased. The ringing on the SW-node is damped to a large degree,
reducing the electromagnetic interference generated by the switching regulator to a great extent.
9.3.6 Adjustable Output Voltage (TPS61000 and TPS61007 Only)
The accuracy of the internal voltage reference, the controller topology, and the accuracy of the external resistor
divider determine the accuracy of the adjustable output voltage versions. The reference voltage has an accuracy
of ±4% over line, load, and temperature. The controller switches between fixed frequency and pulse-skip mode,
depending on load current. This adds an offset to the output voltage that is equivalent to 1% of VO. Using 1%
accurate resistors for the feedback divider, a total accuracy of ±6% can be achieved over the complete
temperature and output current range. The TPS61007 is an improved adjustable output voltage version. Ground
shift in the feedback loop was eliminated by adding a separate ground pin for the feedback resistor divider
(FBGND).
9.4 Device Functional Modes
9.4.1 Power Save Mode
The TPS6100x enters a power-save mode, minimizing switching losses of the converter. In this mode, the
controller only switches if the output voltage trips below a set threshold voltage. It ramps up the output voltage
with one or several pulses, and again goes into the power-save mode once the output voltage exceeds the
threshold voltage.

10.2.2 Detailed Design Procedure
10.2.2.1 Programming the TPS61000 and TPS61007 Adjustable Output Voltage Devices
The output voltage of the TPS61000 and TPS61007 can be adjusted with an external resistor divider. The typical
value of the voltage on the FB pin is 500 mV in fixed-frequency operation and 485 mV in the power-save
operation mode. The maximum allowed value for the output voltage is 3.3 V. The current through the resistive
divider should be about 100 times greater than the current into the FB pin. The typical current into the FB pin is
0.01 µA, and the voltage across R4 is typically 500 mV. Based on those two values, the recommended value for
R4 is in the range of 500 kΩ in order to set the divider current at 1 µA. From that, the value of resistor R3,
depending on the needed output voltage VOUT, can be calculated using the following equation:

If, as an example, an output voltage of 2.5 V is needed, a 2-MΩ resistor should be chosen for R3.

internally connected to GND.

10.2.2.2 Programming the Low Battery Comparator Threshold Voltage
The current through the resistive divider should be about 100 times greater than the current into the LBI pin. The
typical current into the LBI pin is 0.01 µA. The voltage across R2 is equal to the reference voltage that is
generated on-chip, which has a value of 500 mV ±15 mV. The recommended value for R2 is therefore in the
range of 500 kΩ. From that, the value of resistor R1, depending on the desired minimum battery voltage (VBAT),
can be calculated using the following equation:
§V

5 5 u ¨ TRIP ± ¸

(2)
For example, if the low-battery detection circuit should flag an error condition on the LBO output pin at a battery
voltage of 1 V, a resistor in the range of 500 kΩ should be chosen for R1.
The output of the low battery comparator is a simple open-drain output that goes active low if the battery voltage
drops below the programmed threshold voltage on LBI. The output requires a pullup resistor with a
recommended value of 1MΩ, and should only be pulled up to the VOUT. If not used, the LBO pin can be left
floating.
10.2.2.3 Inductor Selection
The output filter of inductive switching regulators is a low pass filter of second order. It consists of an inductor
and a capacitor, often referred to as storage inductor and output capacitor.
To select an inductor, keep the possible peak inductor current below the current limit threshold of the power
switch in your chosen configuration. For example, the current limit threshold of the TPS61006’s switch is 1100
mA at an output voltage of 3.3 V. The highest peak current through the inductor and the switch depends on the
output load, the input (VBAT), and the output voltage (VOUT). Estimation of the maximum average inductor current
can be done using the following equation:
VOUT
I L IOUT u
VBAT u 0.8
(3)
For example, for an output current of 100 mA at 3.3 V, at least 515-mA current flows through the inductor at a
minimum input voltage of 0.8 V.
The second parameter for choosing the inductor is the desired current ripple in the inductor. Normally it is
advisable to work with a ripple of less than 20% of the average inductor current. A smaller ripple reduces the
magnetic hysteresis losses in the inductor as well as output voltage ripple and EMI. But in the same way, the
regulation time at load change rises. In addition, a larger inductor increases the total system cost.
With those parameters it is possible to calculate the value for the inductor:
9BAT u 9OUT ± 9BAT
L
', L u ¦ u 9OUT
where
•
•
f is the switching frequency
ΔIL is the ripple current in the inductor, that is 20% x IL
(4)
In this example, the desired inductor has the value of 12 µH. With this calculated value and the calculated
currents, it is possible to chose a suitable inductor. Care has to be taken that load transients and losses in the
circuit can lead to higher currents as estimated in equation 3. Also, the losses in the inductor caused by magnetic
hysteresis losses and copper losses are a major parameter for total circuit efficiency.
The following inductors from different suppliers were tested. All work with the TPS6100x converter within their
specified parameters:

10.2.2.4 Capacitor Selection
The major parameter necessary to define the output capacitor is the maximum allowed output voltage ripple of
the converter. This ripple is determined by two parameters of the capacitor, the capacitance and the ESR. It is
possible to calculate the minimum capacitance needed for the defined ripple, supposing that the ESR is zero.

¦ u '9 u 9OUT
where
•
•
f is the switching frequency
ΔV is the maximum allowed ripple.
(5)
With a chosen ripple voltage of 15 mV, a minimum capacitance of 10 µF is needed. The total ripple will be larger
due to the ESR of the output capacitor. This additional component of the ripple can be calculated using the
following equation:
'VESR IOUT u RESR
(6)
An additional ripple of 30 mV is the result of using a tantalum capacitor with a low ESR of 300 mΩ. The total
ripple is the sum of the ripple caused by the capacitance and the ripple caused by the ESR of the capacitor. In
this example, the total ripple is 45 mV. It is possible to improve the design by enlarging the capacitor or using
smaller capacitors in parallel to reduce the ESR or by using better capacitors with lower ESR, like ceramics. For
example, a 10-µF ceramic capacitor with an ESR of 50 mΩ is used on the evaluation module (EVM). Tradeoffs
have to be made between performance and costs of the converter circuit.
A 10-µF input capacitor is recommended to improve transient behavior of the regulator. A ceramic capacitor or a
tantalum capacitor with a 100-nF ceramic capacitor in parallel placed close to the IC is recommended.
10.2.2.5 Rectifier Selection
The rectifier diode has a major impact on the overall converter efficiency. Standard diodes are not suitable for
low-voltage switched mode power supplies. A Schottky diode with low forward voltage and fast reverse recovery
should be used as a rectifier to minimize overall losses of the dc-dc converter. The maximum current rating of the
diode must be high enough for the application. The maximum diode current is equal to the maximum current in
the inductor that was calculated in equation 3. The maximum reverse voltage is the output voltage. The chosen
diode should therefore have a reverse voltage rating higher than the output voltage.

The typical forward voltage of those diodes is in the range of 0.35 to 0.45 V assuming a peak diode current of
600 mA.
10.2.2.6 Compensation of the Control Loop
An R/C/C network must be connected to the COMP pin in order to stabilize the control loop of the converter.
Both the pole generated by the inductor L1 and the zero caused by the ESR and capacitance of the output
capacitor must be compensated. The network shown in Figure 18 satisfies these requirements.

Figure 18. Compensation of the Control Loop
Resistor RC and capacitor CC2 depend on the chosen inductance. For a 33-µH inductor, the capacitance of CC2
should be chosen to 33 nF, or in other words, if the inductor is xx µH, the chosen compensation capacitor should
be xx nF, the same number value. The value of the compensation resistor is then chosen based on the
requirement to have a time constant of 0.3 ms for the R/C network of RC and CC2; hence for a 33-nF capacitor, a
10-kΩ resistor should be chosen for RC.
Capacitor CC1 is depending on the ESR and capacitance value of the output capacitor, and on the value chosen
for RC. Its value is calculated using following equation:

For a selected output capacitor of 22 µF with an ESR of 0.2 Ω, and RC of 33 kΩ, the value of CC1 is in the range

11 Power Supply Recommendations
The device is designed to operate from an input voltage supply range between 0.8 V and 3.3 V. This input supply
must be well regulated. If the input supply is located more than a few inches from the converter, additional bulk
capacitance may be required in addition to the ceramic bypass capacitors. An electrolytic or tantalum capacitor
with a value of 47 μF is a typical choice.
12 Layout
12.1 Layout Guidelines
For all switching power supplies, the layout is an important step in the design, especially at high peak currents
and high switching frequencies. If the layout is not carefully done, the regulator could show stability problems as
well as EMI problems. Therefore, use wide and short traces for the main current path and for the power ground
tracks. The input capacitor, output capacitor, and the inductor should be placed as close as possible to the IC.
Use a common ground node for power ground and a different one for control ground to minimize the effects of
ground noise. Connect these ground nodes at any place close to one of the ground pins of the IC. The feedback
divider should be placed as close as possible to the control ground pin of the IC. To lay out the control ground, it
is recommended to use short traces as well, separated from the power ground traces. This avoids ground shift
problems, which can occur due to superimposition of power ground current and control ground current.

12.3 Thermal Considerations
Implementation of integrated circuits in low-profile and fine-pitch surface-mount packages typically requires
special attention to power dissipation. Many system-dependent issues such as thermal coupling, airflow, added
heat sinks and convection surfaces, and the presence of other heat-generating components affect the power
dissipation limits of a given component.
Three basic approaches for enhancing thermal performance are listed below:
• Improving the power dissipation capability of the PWB design
• Improving the thermal coupling of the component to the PWB
• Introducing airflow in the system
The maximum junction temperature (TJ) of the TPS6100x devices is 125°C. The thermal resistance of the 10-pin
MSOP package (DGS) is RθJA = 161°C/W. Specified regulator operation is assured to a maximum ambient
temperature (TA) of 85°C. Therefore, the maximum power dissipation is about 248 mW. More power can be
dissipated if the maximum ambient temperature of the application is lower.

Under normal operating conditions, the sum of all losses generated inside the converter IC is less than 50 mW,
which is well below the maximum allowed power dissipation of 248 mW as calculated in Equation 8. Therefore,
power dissipation is given no special attention.
Table 6 shows where the losses inside the converter are generated.
