REFLLCBUCK4CH320WTOBO1 is a reference design that demonstrates 320W high-power LED driver circuit with four Constant Current (CC) output channels. It consists of a dual-stage half-bridge LLC and a separated PFC stage with high-precision secondary-side controlled constant voltage output realized by the ICL5102 LED driver IC. For precise current control, as well as deep dimming down to 0.5% and flicker-free light on the secondary side a buck topology such as realized with the ILD8150E is the ideal choice. The primary stage utilizes a combo controller with DCM PFC which enables significant cost savings compared to CCM PFC mode that is commonly deployed at such high power levels. In addition the dedicated lighting IC ICL5102 ensures very low THD and high power factor over voltage and load variations. The reference board offers excellent output voltage accuracy of typically +/-4% across a universal input voltage range from 90 to 305VAC and wide output current range from 0 to 4.35A.
