Page 2 1 Evaluation Module Overview 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.

Page 4 SP devices, the chip resistors are each rated for only 2W. When utilizing the transient circuit on the TPS7H4011QEVM-CVAL, the signal sent to the MOSFET gate through TP20 (TRANS) can be modulated to keep the average power through the load resistors below the 2W rating.
Page 5 Some components can reach high temperatures > 55°C when the board is powered on. Do not touch the board at any point during operation or immediately after operating, as high temperatures can be present.
