Synchronous Buck Converter Reference Design for Automotive Instrument Clusters

PMP20682

 
Overview

PMP20682 is a synchronous buck converter reference design using the LM5141-Q1 synchronous buck controller IC. This design accepts input voltages from 5V to 40V and provides a 3.3V output capable of delivering 10A to the load. The input contains an EMI filter. Optional frequency jitter and slew rate control features are available for additional EMI control. This design provides mounting holes for the bottom MOSFET heat sink.
