336-W auxless AC/DC power supply reference design with 80 PLUS platinum compatible performance
Description
This reference design uses UCC28056 CRM/DCM PFC controller and UCC256304 enhanced LLC controller with integrated driver to provide 24-V/10-A output (continuous: 14-A peak) from universal AC input. This design achieves 92.8% peak efficiency at 115-Vac input and 94.9% peak efficiency at 230-Vac input. The efficiency and power factor numbers also meet both 115-V and 230-V internal 80 PLUS Platinum specifications and DoE level VI requirement.
