Beschreibung
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.
