40W Synchronous ZETA Converter with Two Inductors Reference Design

PMP9581_REVC

Design files

Overview

This dual-inductor, 13.2V at 4A, synchronous ZETA converter achieves greater than 93% efficiency at full load. It is capable of 5A out for Vin greater than 10V. It utilizes all surface mount components, maintains a low temperature rise and is capable of high peak load transients.  See PMP9581 REVB for this design with a coupled inductor.

Features
  • Fully synchronous ZETA converter
  • Efficiency approaches 94% at full load
  • Utilizes two separate inductors
  • Board length approaches 70 mm
  • Capable of 5A output with any input
  • Test report available
