Texas Instruments LMR66430 | Demoboard LMR66430-2EVM

Description

The LMR664x0 is a small 36-V, 3-A (available in 2-A and 1-A variants) synchronous step-down DC/DCconverter in an enhanced HotRod QFN package.This easy-to-use converter supports a wide inputvoltage range of 2.7 V to 36 V (after start-up or afteroperating) with transients up to 42 V.

Features

Functional Safety-Capable– Documentation available to aid functional safetysystem design
