Design files

Overview

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
Output voltage options PMP10900.1
Vin (Min) (V) 4.5
Vin (Max) (V) 5.5
Vout (Nom) (V) 3.3
