The BD6142AMUV is a high‑efficiency PWM step‑up DC/DC LED driver designed for medium to large LCD backlights. It integrates a 50 V N‑channel MOSFET, offers eight matched current‑driver channels (max 30 mA each), and includes extensive safety functions such as over‑voltage, over‑current, and thermal shutdown.
Typical applications include notebook and net‑book displays, monitors, portable DVD players, and other LCD equipment. The device is supplied in a compact 4.0 × 4.0 × 1.0 mm VQFN package, making it suitable for space‑constrained designs.
