TPSM13604H Overview
A power module is a complete DC-DC converter solution that integrates the controller, power FETs, inductor, and often compensation circuitry into a single package. This integration simplifies PCB layout, reduces design time, and improves thermal performance compared to discrete solutions. The TPSM13604H belongs to the SIMPLE SWITCHER family, which is known for its ease of use and robust performance in industrial, automotive, and communications applications.
Key features include a wide input voltage range of 5V to 36V, adjustable output voltage down to 3V, and a maximum output current of 4A. The module offers exceptional power conversion efficiency, line and load regulation, and output accuracy. It includes protection features such as thermal shutdown, input undervoltage lockout, output over-voltage protection, short-circuit protection, and output current limit. Additionally, it supports start-up into a pre-biased output and allows the switching frequency to be adjusted up to 700 kHz with a single resistor.
The TPSM13604H uses an innovative package that enhances thermal performance and allows for hand or machine soldering. The 7-TO-PMOD package is designed for surface-mount assembly and provides excellent heat dissipation. The module operates over a junction temperature range of -40°C to +125°C, making it suitable for harsh environments.
Typical applications include point-of-load (PoL) converters for FPGAs, ASICs, and microprocessors, as well as industrial control systems, test and measurement equipment, and automotive infotainment systems. The wide input range and high output current make it ideal for systems powered from 12V or 24V rails.
When designing with the TPSM13604H, ensure proper input and output capacitance to maintain stability and minimize ripple. The adjustable output voltage is set by an external resistor divider, and the switching frequency can be programmed with a single resistor. Adequate thermal management is essential when operating at high output currents and high input-to-output voltage differentials.

Design Notes
Place input and output capacitors as close to the module pins as possible to minimize parasitic inductance and ensure stable operation. Use low-ESR ceramic capacitors with adequate voltage rating. For the TPSM13604H, a 10uF input capacitor and a 22uF output capacitor are recommended, but refer to the datasheet for exact values based on output voltage and load.
The TPSM13604H can dissipate significant power at high output currents and high input-to-output voltage differentials. Ensure adequate copper area on the PCB for heat spreading, and consider adding thermal vias to the ground plane. The 7-TO-PMOD package is designed for enhanced thermal performance, but proper layout is essential to keep the junction temperature within limits.
Do not exceed the maximum input voltage of 36V. Ensure the feedback resistor divider uses 1% tolerance resistors to maintain output voltage accuracy. The switching frequency programming resistor must be selected according to the datasheet formula to avoid instability. Also, verify that the output capacitor meets the minimum ESR requirements to prevent oscillation.
