Typical Applications
TPSM82813 is suitable for 6 applications: FPGA / ASIC Point-of-Load Power, Telecommunication Equipment, Test and Measurement Instruments, Medical Equipment, Industrial Sensors and Automation, Portable and Battery-Powered Instruments.
FPGA / ASIC Point-of-Load Power
The TPSM82813 fits FPGA point-of-load supplies because its 0.6V-5.5V adjustable output covers modern core rails down to 0.6V while delivering 3A continuously. Adjustable soft-start and voltage tracking satisfy rail sequencing requirements, and the fixed-frequency peak current-mode control provides fast transient response during logic bursts. Placed near the FPGA with recommended ceramic output capacitance, the integrated inductor shrinks the solution height and area versus a discrete buck. Power good output enables downstream rail monitoring.
Recommended
Telecommunication Equipment
Telecom line cards and network processors need dense, efficient 5V-bus to low-voltage conversions, and the TPSM82813 converts 2.75V-6V input to any 0.6V-5.5V rail at 3A with up to 95% efficiency. Optional frequency synchronization lets multiple modules switch at a common clock, simplifying EMI filter design across dense boards, while spread spectrum reduces peak emissions. Its integrated inductor reduces assembly complexity for high-volume telecom manufacturing.
Recommended
Test and Measurement Instruments
Test instruments require clean, stable, well-characterized rails. The TPSM82813's fixed-frequency peak current-mode control gives predictable switching behavior, and frequency synchronization prevents beat-frequency artifacts between multiple converters that would appear on sensitive measurement channels. The 3A rating with 0.6V minimum output supports powering ADC/DAC and processor rails, and the adjustable UVLO protects against brownout during supply dips.
Recommended
Medical Equipment
Medical device power supplies benefit from the TPSM82813's high efficiency (up to 95%), which reduces internal heat rise in enclosed patient-adjacent enclosures, and its small integrated-inductor footprint that frees board space for isolation and signal-conditioning circuitry. Adjustable soft-start prevents inrush transients during turn-on, and tracking supports safe multi-rail sequencing for mixed-signal medical electronics such as patient monitors and diagnostic front ends.
Recommended
Industrial Sensors and Automation
Industrial 5V buses feeding sensor nodes and controller I/O map directly onto the TPSM82813 input range of 2.75V-6V, delivering adjustable 0.6V-5.5V outputs at 3A. Spread spectrum operation eases compliance in electrically noisy factory environments, the adjustable UVLO ensures clean startup on sagging supply lines, and the power good flag gives the system controller a health indicator. The robust current-mode architecture tolerates wide line and load variation typical of industrial plants.
Recommended
Portable and Battery-Powered Instruments
With 2.75V minimum input, the TPSM82813 runs directly from a single Li-ion cell (3.0V-4.2V), making it suitable for battery-powered test tools and portable instruments. Light-load efficiency mode extends battery runtime during idle periods, and up to 95% peak efficiency minimizes wasted energy. The integrated inductor keeps the power section compact for handheld enclosures, while 0.6V-5.5V output flexibility serves both processor and analog rails.

Key Differentiators
- Integrated inductor in a pin-to-pin scalable family (vs TPSM82816)
- Lower cost at moderate loads (vs TPSM82816)
- Battery-friendly input range (vs TPSM82810)
Design Notes
Follow the recommended land pattern in the TPSM8281x datasheet. Place the input ceramic capacitors (per datasheet recommendation) as close as possible to the VIN and GND pins. Use thermal vias under and around the module per the recommended pattern - the integrated inductor concentrates heat in the package, and via arrays are the primary path to internal ground planes for dissipation.
Configure the adjustable soft-start capacitor to control inrush when the module powers large FPGA or processor load capacitance. If the system requires rail sequencing, use the tracking input to make VOUT follow a master rail during ramp-up. Set the UVLO divider so the module disables below the minimum voltage your source can reliably supply at full 3A load.
Enable spread spectrum in EMI-sensitive systems to reduce peak radiated emissions around the switching frequency. For multi-module boards, synchronize all TPSM8281x modules to a common external clock to avoid beat-frequency interference with sensitive analog or RF circuitry. Keep the switching-node area small by minimizing loop area under the module.
Do not exceed the 6V absolute maximum input; transient spikes on 5V industrial buses can exceed this - add input TVS if needed. Verify the output resistor divider uses 1% or better tolerance for output accuracy. When swapping family members (e.g., TPSM82816 for higher current), confirm the same package option (QFN vs MagPack SIL) matches your land pattern - the two footprints differ.
Compliance Information
