1.1 Introduction

The TPSM843521 is a single, PCM control mode, synchronous buck module requiring a very low external component count. The TPSM843521 synchronous buck converter used in the EVM has the following features:

  • 3.8V to 18V input voltage range
  • 0.6V to 9V output voltage range
  • Support 5A continuous output current
  • 0.6V±1.0% output voltage accuracy
  • Selectable switching frequency of 200kHz and 2200kHz
  • Selectable Adjustable Soft-start time/PG function
  • Selectable Eco-mode and FCCM under light load operation

This user's guide describes the characteristics, operation, performance, and use of the Texas Instruments TPSM843521 evaluation module (EVM). The TPSM843521 is designed to help users easily evaluate and test the operation and functionality of the TPSM843521. This user's guide includes the following:

  • Setup instructions for the hardware
  • Printed-circuit board layouts for the EVM
  • Schematic diagram
  • Bills of material
  • Test results for the EVM
