PMP4484.5, DC Input, 6 Channel LED Strings with 30W Output Reference Design. The PMP4484 is a power reference design with AC input. It is a isolated LED driver, provides 6 channel LED outputs with PWM dimming. It implements a high PF flyback controller UCC28810 to output DC 40V, the Constant Current Buck LED Driver LM3414HV downs the voltage to 30V to drive LED. The design also provides 3.3Vo to MCU by the buck controller LMR16006 and a 10Vo to RS485. The system achieves high efficiency and high PF
