- Adjustable output voltage up to 16V (vs TPSM82822A)
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.
