NCP5612 is Onsemi's ultra small white LED driver dedicated to LCD display backlighting. It provides 90% peak efficiency and 0.2% LED to LED matching.
The NCP5612 provides two LED outputs dedicated to LCD backlight applications. It uses a high‑efficiency charge‑pump DC/DC converter with 1× and 1.5× operating modes and delivers up to 87% peak efficiency. The device supports a Single Wire Serial Link protocol for digital control and offers programmable dimming with 16 current steps.
Typical applications include portable backlights, cellular phone camera flash, and simultaneous LCD and keyboard driving. The part is supplied in a Pb‑free LLGA12 (2 × 2 mm) package and includes built‑in short‑circuit and open‑load protection, as well as tight LED‑to‑LED matching tolerance of 0.2%.
