The On-Bright OB3362F datasheet details a 4‑channel high‑performance LED driver for LCD backlight applications, covering features, specifications, pinout…
The OB3362F is a highly integrated LED driver designed for LCD backlight systems. It combines a fixed‑frequency boost converter, a 10 V gate‑drive regulator and four matched current‑source channels, each capable of up to 200 mA, to drive multiple LED strings while minimizing component count.
The device offers both internal burst‑mode dimming and external PWM dimming, programmable operating frequency (100 kHz‑600 kHz), and extensive protection features such as over‑voltage, under‑voltage lockout, open/short LED protection and thermal shutdown. Recommended layout guidelines and a reference application circuit are also provided.
