310W PSU Using Transition Mode Bridgeless PFC and LLC-SRC - Reference Design
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
Applications
- LED power supply
- DIN rail power supply
- Rack & server PSU with 48-V output
- Industrial AC-DC
