180-W universal input PFC + LLC TV power supply reference design
Description
This AC to DC power supply design for TV application provides 12-V: 5-A and 150-V: 0.8-A output from universal AC voltage (90 Vac to 264 Vac). The design uses CRM/DCM PFC controller UCC28056: and LLC controller UCC256404 with enhanced burst mode which enabled for low standby power and smaller audible noise. The design achieves 93% peak efficiency at 230-Vac input.
Features
- Low profile design with single layer board achieves maximum board height of 16 mmEnhanced burst mode operation minimized audible noise at no load and standbyProvides efficient power conversion with greater than 93% peak efficiencyLess than 300-mW standby power consumption with 150-mW load.
