Overview

PMP10534 is a single-phase synchronous buck converter using the LM53603 regulator IC, which contains integrated top-side and bottom-side FETs. The design accepts an input voltage of 7Vin to 36Vin and provides an output of 5Vout capable of supplying 3A of continuous current to the load.

Features
  • Automotive AEC Q1 qualified
  • Synchronizable to external clock
  • Overload protection
  • Light-load mode for improved efficiency
  • Integrated high-side and low-side FETs
  • 2.1MHz switching frequency for small solution size
