Description

The LM5137F-Q1-EVM12V evaluation module (EVM) is designed to showcase the LM5137F-Q1 synchronous, buck controller, which is intended for functional safety applications up to ASIL D. The EVM operates as a two-phase interleaved design over an input voltage range of 36V to 72V to deliver a 12V regulated output at up to 20A.
