Texas Instruments UCC28740 | Demoboard PMP30251_RevB

Overview

TopologyFlyback Converter
Input voltage85-264 V
Output 123 V / 2.2 A
IC revisionRevB

Description

The PMP30251 reference design uses the UCC28740 flyback controller to generate an isolated output 23V@2.2A from an universal AC input. The UCC28740 uses an optical coupler to regulate the output and to improve transient response. The valley-switching technique reduces switching losses and keeps the efficiency high.
