EVM User's Guide: TPSM64406EVM-4PH
TPSM64406 4-Phase, 36V, Single 12A Output,
Synchronous, Buck Module Evaluation Module
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.
