Design files

Overview

The PMP20175 reference design is a SEPIC converter that operates from 6.5V - 16Vin and supplies 7V@3A out (21W).  This low cost compact design operates at 600KHz with greater than 90.5% full load efficiency (Vin = 12V).  

Features
  • High switching frequency of 600KHz
  • Greater than 89% full load efficiency over full input voltage range
  • Less than 100mVpp output ripple voltage
  • Implemented with two standard inductors
