PMP4484
具有 30W 輸出的 AC 輸入六通道 LED 燈串參考設計
PMP4484
概覽
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.
特點
- 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
