•
•
•
•
•
•
The TPSM8286xA device family consists of 4-A and
6-A step-down converter power modules optimized
for small solution size and high efficiency. The
power modules integrate a synchronous step-down
converter and an inductor to simplify design, reduce
external components, and save PCB area. The lowprofile and compact solution is suitable for automated
assembly by standard surface mount equipment.
2 Applications
•
•
•
•
•
•
Core supply for FPGAs, CPUs, ASICs
Optical modules
Medical imaging
Industrial transport
Factory automation and control
Aerospace and defense
Tight output voltage accuracy, even with small
output capacitors, is achieved though the DCSControl architecture and its excellent load transient
performance. At medium-to-heavy loads, the
converter operates in PWM mode and automatically
enters Power save mode operation at light load to
maintain high efficiency over the entire load current
range. The devices can also be forced in PWM mode
operation for the smallest output voltage ripple.
The EN and PG pins, which support sequencing
configurations, bring a flexible system design. An
integrated soft start reduces the inrush current
required from the input supply. Overtemperature
protection and hiccup short-circuit protection deliver
a robust and reliable solution.

8 Detailed Description
8.1 Overview
The TPSM8286xA synchronous step-down converter power module is based on DCS-Control (Direct Control
with Seamless transition into power save mode). This is an advanced regulation topology that combines the
advantages of hysteretic, voltage, and current mode control. The DCS-Control topology operates in PWM (pulse
width modulation) mode for medium-to-heavy load conditions and in PSM (power save mode) at light load
currents. In PWM, the converter operates with its nominal switching frequency of 2.4 MHz, having a controlled
frequency variation over the input voltage range. As the load current decreases, the converter enters power
save mode, reducing the switching frequency and minimizing the quiescent current of the IC to achieve high
efficiency over the entire load current range. DCS-Control supports both operation modes using a single building
block and, therefore, has a seamless transition from PWM to PSM without effects on the output voltage. The
TPSM8286xA offers excellent DC voltage regulation and load transient regulation, combined with low output
voltage ripple, minimizing interference with RF circuits.

8.3 Feature Description
8.3.1 Power Save Mode
As the load current decreases, the device seamlessly enters power save mode (PSM) operation. In PSM,
the converter operates with a reduced switching frequency and a minimum quiescent current to maintain high
efficiency. Power save mode is based on a fixed on-time architecture, as shown in Equation 1.

SLUSEF1B – SEPTEMBER 2021 – REVISED NOVEMBER 2022
The switching frequency in PSM is estimated as:
(2)
The load current at which PSM is entered is at one half of the ripple current of the inductor and it can be
estimated as:
(3)
In power save mode, the output voltage rises slightly above the nominal output voltage. This effect is minimized
by increasing the output capacitance.
8.3.2 Forced PWM Mode
After the device has powered up and ramped up VOUT, the VSET/MODE pin acts as a digital input. With a
high level on the VSET/MODE pin, the device enters forced PWM (FPWM) mode and operates with a constant
switching frequency over the entire load range, even at very light loads. This reduces the output voltage ripple
and allows simple filtering of the switching frequency for noise-sensitive applications but lowers efficiency at light
loads.
8.3.3 Optimized Transient Performance from PWM to PSM Operation
For most converters, the load transient response in PWM mode is improved compared to PSM, because the
converter reacts faster on the load step and actively sinks energy on the load release. As an additional feature,
the TPSM8286xA automatically stays in PWM mode for 128 cycles after a heavy load release to bring the output
voltage back to the regulation level faster. After these 128 cycles of PWM mode, it automatically returns to PSM
(if VSET/MODE is low). See Figure 8-1. Without this optimization, the output voltage overshoot is higher.

8.3.4 Low Dropout Operation (100% Duty Cycle)
The device offers a low dropout operation by entering 100% duty cycle mode if the input voltage comes close to
the target output voltage. In this mode, the high-side MOSFET switch is constantly turned on. This is particularly
useful in battery-powered applications to achieve the longest operation time by taking full advantage of the whole
battery voltage range. The minimum input voltage to maintain a minimum output voltage is given by:
VIN (min) = VOUT (min) + IOUT (max) × RDP
(4)
where
•
•
•
VOUT (min) = Minimum output voltage the load can accept
IOUT (max) = Maximum output current
RDP = Resistance from VIN to VOUT (high-side RDS(on) + RDC of the inductor)
8.3.5 Soft Start
After enabling the device, there is a 650-µs enable delay (tDelay) before the device starts switching. The tDelay
time varies with the VSET/MODE resistor used and is longest with a resistance of 249 k or higher. After the
enable delay, an internal soft-start circuit ramps up the output voltage in 1 ms (tRamp). This action avoids
excessive inrush current and creates a smooth output voltage ramp up. This action also prevents excessive
voltage drops of batteries that have a high internal impedance. Figure 8-2 shows the start-up sequence.

The device is able to start into a pre-biased output capacitor. The device starts with the applied bias voltage and
ramps the output voltage to its nominal value.
8.3.6 Switch Current Limit and HICCUP Short-Circuit Protection
The switch current limit prevents the device from high inductor current and from drawing excessive current from
the battery or input voltage rail. Excessive current can occur with a heavy load or shorted output circuit condition.
If the inductor current reaches the threshold ILIM, cycle by cycle, the high-side MOSFET is turned off and the
low-side MOSFET is turned on until the inductor current ramps down to the low-side MOSFET current limit.
When the high-side MOSFET current limit is triggered 256 times, the device stops switching. The device then
automatically re-starts with soft start after a typical delay time of 16 ms has passed. The device repeats
this mode until the high load condition disappears. This HICCUP short-circuit protection reduces the current
consumed from the input supply because the device only draws input current approximately 10% of the time
during an overload condition. Figure 9-29 shows the hiccup short-circuit protection.
The low-side MOSFET also contains a negative current limit to prevent excessive current from flowing back
through the inductor to the input. If the low-side sinking current limit is exceeded, the low-side MOSFET is turned
off. In this scenario, both MOSFETs are off until the start of the next cycle. The negative current limit is only
active in forced PWM mode.

8.3.7 Undervoltage Lockout
To avoid mis-operation of the device at low input voltages, undervoltage lockout (UVLO) disables the device
when the input voltage is lower than VUVLO. When the input voltage recovers, the device automatically returns to
operation with soft start.
8.3.8 Thermal Shutdown
When the junction temperature exceeds TJSD, the device goes into thermal shutdown, stops switching, and
activates the output voltage discharge. When the device temperature falls below the threshold by the hysteresis,
the device returns to normal operation automatically with soft start.

8.4 Device Functional Modes
8.4.1 Enable and Disable (EN)
The device is enabled by setting the EN pin to a logic high. Accordingly, shutdown mode is forced if the EN pin is
pulled low. In shutdown mode, the internal power switches as well as the entire control circuitry are turned off. An
internal switch smoothly discharges the output through the VOS pin in shutdown mode. Do not leave the EN pin
floating.
The typical enable threshold value of the EN pin is 0.66 V for rising input signals and the typical shutdown
threshold is 0.52 V for falling input signals.
8.4.2 Output Discharge
The purpose of the output discharge function is to ensure a defined down-ramp of the output voltage when the
device is disabled and to keep the output voltage close to 0 V. The output discharge is active when the EN pin
is set to a logic low and during thermal shutdown. The discharge is active down to an input voltage of 1.6 V
(typical).
8.4.3 Power Good (PG)
The device has an open-drain power-good pin, which is specified to sink up to 2 mA. The power-good output
requires a pullup resistor connected to any voltage rail less than 5.5 V. The PG signal can be used for
sequencing of multiple rails by connecting it to the EN pin of other converters. Leave the PG pin unconnected
when not used. Table 8-1 shows the typical PG pin logic.

8.4.4 Output Voltage and Mode Selection (VSET/MODE)
The TPSM8286xA family devices are configurable as either an adjustable output voltage or a fixed output
voltage, depending on the needs of each individual application. This feature simplifies the logistics during mass
production, as one part number offers several fixed output voltage options as well as an adjustable output
voltage option. During the enable delay (tDelay), the device configuration is set by an external resistor connected
to the VSET/MODE pin through an internal R2D (resistor to digital) converter. This configures the VREF input
to the error amplifier (EA) to be either the VFB voltage (0.6-V typical) or the selected output voltage. Table 8-2
shows the options.

The R2D converter has an internal current source, which applies current through the external resistor, and an
internal ADC, which reads back the resulting voltage level. Depending on the detected resistance, the output
voltage is set. After this R2D conversion is finished, the current source is turned off to avoid current flowing
through the external resistor. Make sure that the additional leakage current path is less than 20 nA and the
capacitance is not greater than 30 pF from this pin to GND during R2D conversion, otherwise a false VOUT
value is set. For more details, refer to the Benefits of a Resistor-to-Digital Converter in Ultra-Low Power Supplies
White Paper. When the device is set to a fixed output voltage, the FB pin must be connected to the output
directly. See Figure 8-4.

9 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI’s customers are responsible for
determining suitability of components for their purposes, as well as validating and testing their design
implementation to confirm system functionality.
9.1 Application Information
The TPSM8286xA is a synchronous step-down converter power module family. The following section discusses
the selection of the external components to complete the power supply design. The required power inductor
is integrated inside the TPSM8286xA. The integrated shielded inductor has a value of 0.22 µH with a
±20% tolerance. The TPSM82864A and TPSM82866A are pin-to-pin and BOM-to-BOM compatible. The
TPSM8286xAA0HRDMR devices give a higher efficiency than the TPSM8286xAA0SRDJR devices due to their
increased height. For a given package height (RDM or RDJ), the 4A and 6A version give the same efficiency and
performance and are different only in their rated output current.

9.2.2 Detailed Design Procedure
9.2.2.1 Setting The Output Voltage
With the VSET/MODE pin set high or low, an adjustable output voltage is set by an external resistor divider
according to Equation 5:
§V
R1 R2 u ¨ OUT
© VFB
·
1¸
¹
§V
R2 u ¨ OUT
© 0.6V
·
1¸
¹
(5)
To keep the feedback (FB) net robust from noise, set R2 equal to or lower than 100 kΩ to have at least 6 µA
of current in the voltage divider. Lower values of FB resistors achieve better noise immunity but lower light-load
efficiency, as explained in the Design Considerations for a Resistive Feedback Divider in a DC/DC Converter
Technical Brief.
When a fixed output voltage is selected, connect the FB pin directly to the output. R1 and R2 are not needed,
as VOUT is set through a resistor on the VSET/MODE pin. Select the recommended resistor value from the list in
Table 8-2.
9.2.2.2 Input and Output Capacitor Selection
For the best output and input voltage filtering, low-ESR ceramic capacitors are required. The input capacitor
minimizes input voltage ripple, suppresses input voltage spikes, and provides a stable system rail for the device.
The input capacitor must be placed between VIN and PGND as close as possible to those pins. For most
applications, 22 μF is sufficient, though a larger value reduces input current ripple. The input capacitor plays an
important role in the EMI performance of the system as explained in the Simplify Low EMI Design With Power
Modules White Paper.
The architecture of the device allows the use of tiny ceramic output capacitors with low equivalent series
resistance (ESR). These capacitors provide low output voltage ripple and are recommended. The capacitor
value can range from 2 × 22 µF up to 150 µF. The recommended typical output capacitors are 2 × 22 µF or 1 ×
47 µF with an X5R or better dielectric. Values over 150 µF can degrade the loop stability of the converter.
Ceramic capacitors have a DC-Bias effect, which has a strong influence on the final effective capacitance.
Choose the right capacitor carefully in combination with considering its package size and voltage rating. Make
sure that the effective input capacitance is at least 10 µF and the effective output capacitance is at least 22 µF.

9.3 Power Supply Recommendations
The device is designed to operate from an input voltage supply range from 2.4 V to 5.5 V. The average input
current of the TPSM8286xA is calculated as:
(6)
Make sure that the input power supply has a sufficient current rating for the application. The power supply must
avoid a fast ramp down. The falling ramp speed must be slower than 10 mV/μs if the input voltage drops below
VUVLO.
9.4 Layout
9.4.1 Layout Guidelines
A proper layout is critical for the operation of any switched mode power supply, especially at high switching
frequencies. Therefore, the PCB layout of the TPSM8286xA demands careful attention to ensure best
performance. A poor layout can lead to issues like the following:
•
•
•
•
Bad line and load regulation
Instability
Increased EMI radiation
Noise sensitivity
Refer to the Five Steps to a Great PCB Layout for a Step-Down Converter Technical Brief for a detailed
discussion of general best practices. The following are specific recommendations for the TPSM8286xA:
•
•
•
•
•
•
Place the input capacitor as close as possible to the VIN and PGND pins of the device. This placement is
the most critical component placement. Route the input capacitor directly to the VIN and PGND pins avoiding
vias.
Place the output capacitor close to the VOUT and PGND pins and route it directly avoiding vias.
Place the FB resistors R1 and R2 close to the FB and AGND pins and place R4 close to the VSET/MODE pin
to minimize noise pickup.
The sense traces connected to the VOS pin is a signal trace. Take special care to avoid noise being induced.
Keep the trace away from SW.
To improve thermal performance, use GND vias under the exposed thermal pad. Directly connect the AGND
and PGND pins to the exposed thermal pad with copper on the top PCB layer.
Refer to Figure 9-34 for an example of component placement, routing, and thermal design.

The recommended land pattern for the TPSM8286xA is shown at the end of this data sheet. For best
manufacturing results, create the pads as solder mask defined (SMD) when some pins (such as VIN, VOUT,
and PGND) are connected to large copper planes. Using SMD pads keeps each pad the same size and
avoids solder pulling the device during reflow.

9.4.2.1 Thermal Considerations
The TPSM8286xA power module temperature must be kept less than the maximum rating of 125°C. The
following are three basic approaches for enhancing thermal performance:
•
•
•
Improve the power dissipation capability of the PCB design.
Improve the thermal coupling of the component to the PCB.
Introduce airflow into the system.
To estimate the approximate module temperature of the TPSM8286xA, apply the typical efficiency stated in this
data sheet to the desired application condition to compute the power dissipation of the module. Then, calculate
the module temperature rise by multiplying the power dissipation by its thermal resistance. Using this method
to compute the maximum device temperature, the Safe Operating Area (SOA) graphs demonstrate the required
derating in maximum output current at high ambient temperatures. For more details on how to use the thermal
parameters in real applications, see the Thermal Characteristics of Linear and Logic Packages Using JEDEC
PCB Designs Application Report and Semiconductor and IC Package Thermal Metrics Application Report.
