176-VAC to 264-VAC input 24-V 150-W active clamp forward reference design
PMP22495
概述
This reference design uses the UCC2897A active clamp forward controller to convert 176–264 VAC input to a 24 VDC output with a max power of 150 W. The UCC5304 isolated gate driver is used to drive the high-voltage clamp FET. The design achieves > 92% efficiency with diode rectification. Secondary-side current sense provides precise overcurrent protection through a constant current regulation loop. The design passes CISPR 32 conducted emissions testing.
特性
- >92% efficiency with diode rectification
