Dual output SEPIC converter bias power supply reference design for solar panel applications
Overview
| Topology | SEPIC Buck-Boost Topology |
| Input voltage | 7-45 V |
| Output 1 | 3.3 V / 0.5 A |
| Output 2 | 10 V / 0.1 A |
| IC revision | B |
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 EMI
- Dual output SEPIC from single transformer provides excellent cross regulation
- Compact size minimizes required PCB area
Typical applications
- Dual output SEPIC converter bias power supply
