Typical Applications
TPSM82813 is suitable for 6 applications: FPGA Power Supply, Industrial Sensors, Test and Measurement, Networking Equipment, Battery-Powered Devices, Automotive Infotainment.
FPGA Power Supply
The TPSM82813 provides a compact, efficient power solution for FPGA core and I/O rails. With 3A output and adjustable voltage from 0.6V to 5.5V, it can power various FPGA supplies. The integrated inductor reduces board space, and the power good output aids in sequencing. Its fast transient response ensures stable operation under dynamic loads, while the spread spectrum feature minimizes EMI in sensitive designs.
Recommended
Industrial Sensors
In industrial sensor applications, the TPSM82813 offers a reliable power supply from 24V or 12V buses, stepping down to 3.3V or 5V for sensor electronics. Its wide input range and high efficiency reduce heat in enclosures. The adjustable soft-start prevents inrush current spikes, and the tracking feature allows coordinated power-up with other rails. The small QFN package fits into space-constrained sensor housings.
Recommended
Test and Measurement
The TPSM82813 is ideal for test and measurement equipment requiring clean, stable power rails. Its low output noise and high PSRR ensure accurate measurements. The frequency synchronization feature allows alignment with system clocks, reducing interference. The module's integrated inductor simplifies layout, and the power good output enables reliable system monitoring. It can power ADCs, DACs, and digital logic from a single 5V input.
Recommended
Networking Equipment
For networking equipment like routers and switches, the TPSM82813 provides efficient point-of-load conversion from 5V or 12V rails. Its high efficiency reduces thermal stress in dense enclosures. The spread spectrum feature helps meet EMI standards, and the adjustable soft-start prevents power glitches during hot-swap. The module's small footprint allows high component density on PCBs.
Recommended
Battery-Powered Devices
The TPSM82813 is well-suited for battery-powered devices due to its high efficiency and low quiescent current. It can step down from a 2-cell Li-ion battery (up to 6V) to a stable 1.8V or 3.3V rail. The light-load efficiency feature maintains high efficiency at low currents, extending battery life. The small package and integrated inductor are ideal for portable designs.
Recommended
Automotive Infotainment
Although not AEC-Q100 qualified, the TPSM82813 can be used in non-safety automotive infotainment systems where standard-grade parts are acceptable. It provides a stable 3.3V or 5V rail from the car battery (with appropriate protection). The wide input range handles voltage transients, and the spread spectrum reduces EMI in the cabin. For safety-critical applications, use automotive-qualified alternatives.

Design Notes
Follow the recommended land pattern in the datasheet, including 18 vias for thermal dissipation. Place input and output capacitors close to the module to minimize parasitic inductance. Use a solid ground plane underneath the module for optimal thermal and electrical performance.
The TPSM82813's thermal performance is simulated on a PCB defined by JEDEC 51-7. Ensure adequate copper area and vias to dissipate heat, especially at high output currents. The MagPack™ package is designed for efficient heat transfer, but proper PCB design is essential.
Do not exceed the input voltage rating of 6V. Use appropriate input capacitance to handle transient currents. Configure the soft-start and tracking features correctly to avoid inrush current issues. Verify the frequency synchronization range to ensure proper operation.
Compliance Information
