Description

The PMP4862 reference design drives three separate LED strings (up to 77V) at 350mA from a universal AC input. The UCC28810 is used in a PFC-Flyback configuration to provide power factor correction and isolation at the same time. Each LED driver uses one TPS40210 to control the individual LED current. PWM dimming, ON/OFF control, current monitoring, and a trim function are all provided for each individual LED string. The PFC-flyback is over 87% efficient, while the buck LED drivers are over 92% efficient. The overall efficiency is over 80%.
