Description
This resonant converter reference design takes a 380-V to 420-V DC input and generates a 48-V up to 550-W output. With the UCC256302 driver-integrated resonant converter controller and UCC24624, a two-channel synchronous rectifier (SR) driver, this design can achieve 97.95% peak efficiency.
Features
- 110-kHz resonant frequency
- 400-V to 48-V/550-W conversion
- 97.95% efficiency at 380-V input
- 3.45" x 4.95" x 1.4" board dimension
