300-W PFC plus Resonant LLC Half-Bridge controller off-line AC/DC PSU Module

TIDA-00520

Design files

Overview

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.

Features
  • 88.9% @115V, 90.6% @230V average efficiency
  • 83.68% @115V, 85.07% @230V 10% load efficiency 
  • High Power factor 99.5%, 6% typical THD @230Vac 50Hz
  • Less than 200mW No-Load-Power @115Vac acheivable in Auxulliary Self-BIAS mode
  • 397ms turn-on time
  • Line Brownout Protection

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
