DT8211 - LCD Back Light Inverter Driver

Description

2.

Features

  • The DT8211 is a LCD backlight inverter controller for driving CCFL (Cold Cathode Fluorescent Lamp). It drives a half bridge topology symmetrically 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 char.
