PMP4302B, 90 to 264Vac In 100W 4x500mA LED Lighting Driver W/O Aux Flyback Power Supply f/Vcc Reference Design

PMP4302B, reference design uses multi-transformer LLC controller UCC25710 and transition mode PFC controller UCC28810 to develop a 100W four strings with 500mA per string output for general LED lighting driver. The key benefits for this solution are high efficiency, high power factor and good current matching. Meanwhile, the reference design uses innovative self start up circuit to supply Vcc on the primary side (UCC28810) and secondary side (UCC25710) and it does not use any auxiliary Flyback to power main controllers. The application can be used in general LED lighting such as street light and commercial light
