This reference design uses the UCC28C42 boost controller and the UCC28780 active-clamp flyback controller to generate an isolated output of 24 V at 3.5 A over an ultra-wide input voltage range of 20 V to 375 V. The design also uses the UCC24612 synchronous rectifier controller on the secondary side. Zero voltage switching (ZVS) ensures high efficiency over a wide operating range.
