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 <250-mW standby power with 150-mW load and >93% peak efficiency at 230-Vac input.

Features
  • Low profile design with single layer board achieves maximum board height of 16 mm
  • Enhanced burst mode operation minimized audible noise at no load and standby
  • Provides efficient power conversion with greater than 93% peak efficiency
  • Less than 300-mW standby power consumption with 150-mW load.
