Silan SD42509 White LED Driver Chip Datasheet
The SD42509 is a buck‑type LED driver IC that uses current‑mode control and a fixed 280 kHz switching frequency. It integrates a 0.25 Ω power MOSFET, over‑temperature protection and per‑cycle over‑current protection, delivering up to 1 A output current while maintaining load current variation within ±1 % over a wide input voltage range.
Typical applications include driving single or multiple white LEDs in lighting modules, with recommended external components such as input capacitors >10 µF, output capacitors ≥4.7 µF, and inductors around 47 µH for 1 A operation. The device is supplied in an SOP‑8‑225‑1.27 package and is intended for use in consumer and industrial LED lighting designs. This manual is written in Chinese.
