48-V/550-W resonant converter reference design


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.
