The PMP21098 reference design uses UCC28056 transition mode PFC controller and UCC25630 enhanced LLC controller with integrated driver to provide 12V/10.8A output (continuous: 14.2A peak) from universal AC input. This design achieves 91.8% peak efficiency at 115VAC input and 93.4% peak efficiency at 230VAC input. The efficiency and power factor numbers also meet both 115V and 230V internal 80 PLUS gold specifications. In addition: the design is able to achieve less than 300mW power consumption at no load without turning off PFC.
