LM5066IEVM-626 Evaluation Module (EVM)

This user’s guide describes the LM5066I EVM (LM5066IEVM-626). LM5066IEVM-626 contains evaluation
and reference circuitry for the LM5066I. The LM5066I device combines a high performance hot swap
controller with a PMBus™ compliant SMBus/I

C interface to accurately measure, protect, and control the

electrical operating conditions of systems connected to a backplane power bus.
