适用于 2 个 LED 灯串的恒定电流输入升压转换器参考设计
PMP10523
概述
This reference design is a constant current input boost converter for LEDs which utilizes the LM5020-2 controller. The design features switch current limiting and input under-voltage lockout. Input voltage regulation from a constant current source provides constant output power to the load. For LEDs with relatively constant output voltage, the output current is proportional to the input current.
特性
- 85V 230mA constant current input, 141V @ 130mA out
- 18.5W out at 94% peak efficiency
- 2 layer board
- Regulates vin for constant output power
- Output current is proportional to input current for LED loads
