Description

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 degisn also provides 3.3Vo to MCU by the buck conller LMR16006, and a 10Vo to RS485. The system achieves high efficiency and high PF.

Features
  • Isolated single stage Flyback and Buck togology
  • 6 channel LED outputs with PWM dimming
  • Include 3.3Vo for MCU and 10Vo for RS485 power supply
  • High efficiency, 86.4% at 230Vac input
  • High PF, 0.939 at 230Vac input
  • Size: 300mmX22mmx22mm
