Описание :

The DT8211 is a LCD backlight inverter controller for driving CCFL (Cold Cathode Fluorescent Lamp). It drives a half bridge topologysymmetrically and provides a near sinusoidal current waveform. It operates at a single-stage topology, constant frequency PWM (Pulse Width Modulation) mode. The MaxDuty technique achieves the maximum duty ratio of about 48% and hence can provide better efficiency . A typical operating frequency ranges from 30kHz to 300kHz, depending on the CCFL and transformer characteristics. Features such as OLP (Open Lamp Protection) and SCP (ShortCircuit Protection) functions areincluded. Itis available in 18-pin SOPW.
