Low-Line Wide Input LLC Resonant Conv for Consumer Electronics (12V@10A) Reference Design

PMP8762

Design files

Overview

The PMP8762 reference design provides a 12V/10A output from a low line-input voltage (100Vac to 132Vac) with a single LLC resonant converter stage. This design is featured with its low circuit cost, low electromagnetic interference (both conduction and radiation), and high efficiency (over 87% @ full load). This design uses the UCC25600 resonant converter controller to control the LLC resonant converter.
