HIGH-EFFICIENCYACTIVE CLAMP FLYBACKCONVERTER DESIGN

Abstract

The reference design is developed for evaluating 13-W isolated active clamp flyback
Powered Devices converter using the IEEE802.3 at Power Over Ethernet interface and DC/DC
controller TPS23756. The converter is capable of supporting the 13-W permitted IEEE802.3 at
power requirements. It presents good efficiency, load regulation and associated electrical
performance. It supports IEEE802.3 at compliant power devices. This combines PowerOver
Ethernet Poawered Device and DC/DC controller simplifies the model. It provides high efficiency
and better EMI performance with soft-switching technology. All the measurements were done using
the DC source to stimulate Power Over Ethernet Power Supply Equipment. A isolated active clamp
flyback converter with hiccup protection reference design is implemented in Printed Circuit Board.
