Description

PMP10900 is designed to provide a 3.3V/5A output from 5V input. A two-stage LC filter is used to reach output ripple voltage <1mV.

Features
  • Sub-1mV output ripple with two-stage LC
  • 750kHz switching frequency for small solution size
  • Simple compensation using current-mode control
  • The two-stage buck converter solution is built and fully tested. Schematic, BOM and test report are available
