Description

This coupled-inductor, 13.2V at 4A, synchronous ZETA converter achieves greater than 95% 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 REVC for this design with seperate inductors.

Features
  • Fully synchronous ZETA converter
  • Transformer output current is greater than 5A when input is above 10V
  • Efficiency is greater than 95% at full load
  • Board length is approximately 70 mm
  • Test report available
