100VAC-265VAC 100W High Bay LED Lighting (80V @ 350mA)
PMP4862.2: 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%.

Direct Type/ Local Dimming (Conventional TV power + Boost + LED driver)
PMP4298: In this topology, the UCC28051 is a boost transition mode (TM) power factor corrector (PFC), which can rectify an AC input line voltage to 380V DC; the resonant LLC stage UCC25600 regulates the output to 24V/2A for an audio amplifier with feedback to the LLC controller, and 48V for the LED driver input. The flyback with UCC28610 in parallel generates 5V/3A for the system board and 5V/1A for standby power. In the LED driver stage, the 48V input voltage requires another front end boost stage to boost the output voltage to 80V, which connects to the eight-channel TLC5960 with 20LEDs at 120mA per string.This technique is the most common type of current LED backlight; the LLC design is easily implemented. The intelligent headroom voltage monitor (oriHVM™) automatically minimizes the power loss caused by the LED forward voltage change. Only a single additional resistor regulates the boost dc-dc output voltage.
