310W AC-DC PSU with TM-Bridgeless-PFC and LLC-SRC - Reference Design

Overview

TopologyPower Factor Correction
Output 128 V / 12.5 A
IC revisionA

Description

High efficiency, high power factor and reliable power supply are the main focus of the PMP9640 design for motor driver applications. Low cost analog transition mode (TM) PFC controller UCC28051 has been used for bridgeless PFC as the first conversion stage of the PMP9640. LLC series resonant converter (SRC) with UCC25600 is applied as the second stage of the PMP9640. In addition, a high-side buck converter with UCC28710 is applied here as the bias supply. In this design, bridgeless PFC efficiency can go up to 98.5%

Features

  • Universal 85VAC-264VAC input
  • 28V 310W output
  • Up to 98.5% PFC efficiency
  • TM bridgeless PFC output power goes up to 365W
  • AC-DC PSR buck for bias supply

Typical applications

  • LED power supply, Merchant DIN rail power supply, DIN rail power supply,
