1.1 Introduction

The TPS7H4011QEVM-CVAL is the four channel version of the Evaluation Module (EVM) for the ceramic package option of the TPS7H4011 and provides a platform to evaluate multi-channel performance. The four-channel configuration provided by this EVM can source up to 48A of load current to a single output. This user’s guide provides details about the EVM, including the configuration, schematics, and BOM. The EVM is designed to provide flexibility in configuring the device under different conditions. Footprints for additional components and multiple connection options for monitoring device pins are provided. To configure the devices in a custom configuration, please refer to the TPS7H4011-SP and TPS7H4011-SEP 4.5V to 14V Input 12A Radiation Hardened Synchronous Buck Converter data sheet to calculate values of any passives that need to be changed.
