Texas Instruments UCC28740DR | Demoboard PMP10936

85-265VAC Input, 12V/30W Two-Switch Flyback Reference Design

Overview

TopologyFlyback Converter
Input voltage85-265 V
Output 112 V / 2.5 A
IC revisionC

Description

The PMP10936 reference design uses the UCC28740 to provide an isolated 12V at 2.5A output. The UCC24632 is used to control a synchronous recitifer for high efficiency. The two-switch flyback topology recycles the transformer's leakage energy and provides a further improvement in efficiency.
