Texas Instruments TPS549D22EVM | Demoboard TPS549D22EVM-784

TPS549D22 DCAP3 High Performance, 40-A Single Synchronous Step-Down Converter Evaluation Module

Overview

TopologyBuck Converter
Input voltage6-16 V
Output 11 V / 40 A

Description

The PWR784EVM is designed as a single output DC-DC converter that demonstrates the TPS549D22 ina typical low-voltage application while providing a number of test points to evaluate the performance. Ituses a nominal 12-V input bus to produce a regulated 1-V output at up to 40-A load current.
