Description

The TPSM64406 evaluation board showcases the features and performance of the TPSM64406, dual buck DC/DC module with integrated power MOSFETs and inductor. The EVM provides dual 3-A outputs. The output voltages can be individually programmed to a fixed 3.3-V, 5-V or adjustable using external feedback resistors.

The default switching frequency at full load is programmed to 1 MHz. The switching mode at the light load is selectable between FPWM and PFM mode. Each channel can be enabled or disabled by a jumper selection. Finally, spread spectrum can be enabled or disabled by a configuration resistor selection. The TPSM64406EVM is designed to demonstrate the full capabilities of the device on a single PCB design.
