This is a high efficiency 300-W AC/DC reference design. The design can be biased from external supply or configured for Self-Bias Auxillary mode for operation directly off the AC mains. The PFC is fully internally compensated, reducing design complexity and pcb design. Protections include 3-level OCP, line brown-out, PFC Bulk OVP plus UVP and OTP.
