250W Single Stage LLC-SRC Converter Reference Design

Overview

TopologyLLC Resonant Converter
Input voltage102-138 V
Output 124 V
IC revisionB

Description

The PMP9739 is a single stage LLC series resonant converter (SRC), producing up to a 250W output using UCC25600 resonant controller. With the use of single stage LLC-SRC, the converter efficiency goes up to 89% at 250W full output power

Features
