Présentation
Description
MP5921GV‑Z is a high‑efficiency LED driver IC that provides constant‑current regulation for LED strings in compact designs. It uses an external sense resistor to set the LED current and typically integrates a switching regulator/MOSFET for a small, all‑in‑one solution.
Key features (typical):
- Integrated switch MOSFET with constant‑current output
- Adjustable LED current via sense resistor
- Dimming options (PWM and/or analog)
- Wide input voltage range for versatile applications
- Protections: overcurrent, overvoltage, thermal shutdown, short‑circuit protection
- Compact package suitable for small, space‑constrained boards
Typical applications:
- LED backlighting and general illumination
- Display and automotive lighting
Note: For exact electrical specifications, pinout, and recommended PCB/layout guidelines, consult the latest MP5921GV‑Z datasheet from the manufacturer.
