Dual output SEPIC converter bias power supply reference design for solar panel applications

Description

This non-isolated design supplies a regulated 3.3 V/0.5 A and an unregulated 10 V/0.1 A for solar applications.  It operates over a dual solar panel input voltage range of 7 V - 45 V and offers low cost and a compact form factor. This SEPIC converter features minimal voltage ringing on the FET for lower stress and reduced EMI.

Features
  • Eliminates FET voltage ringing for reduced stress and EMIDual output SEPIC from single transformer provides excellent cross regulationCompact size minimizes required PCB area
