Description

This 5V / 6A  solution implements a high efficiency active clamp controller LM5025A and self-drive synchronous rectifier. Input voltage is 18V-40V as typical industrial request and efficiency is 89.5%@24Vin full load. The transformer is embeded into the PCB and 8mm height can be met. The design is suitable for height limited industial applications.

Features
  • Wide input range from 18V to 40V
  • Adjustable Dual Mode Over-Current Protection
  • Active Clamp Forward +S.R controller for high efficiency
  • Lower output ripple voltage with less output capacitor
  • Small form factor: 60mm x 40mm x 8mm
  • Low cost through self-drive secondary synchronous rectifier circuit
