AC Input: 6 Channel LED Strings with 30W Output Reference Design
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 togology6 channel LED outputs with PWM dimmingInclude 3.3Vo for MCU and 10Vo for RS485 power supplyHigh efficiency: 86.4% at 230Vac inputHigh PF: 0.939 at 230Vac inputSize: 300mmX22mmx22mm
Applications
- LED power supply
- Residential lighting
