Description

This TPSM64406 evaluation board showcases the features and performance of multiple TPSM64406 buck DC/DC modules with integrated power MOSFETs and inductors in a multi-phase, single output configuration. The EVM provides a single output capable of loading up to 12A. The output voltages can be individually programmed to a fixed 3.3V, 5V or adjustable using external feedback resistors and jumpers.

The default switching frequency at full load is programmed to 1MHz. 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-4PH is designed to demonstrate the full capabilities of two stacked devices on a single PCB design.
