1. General 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 characteristics. Features such as OLP (Open Lamp Protection) and
SCP (Short Circuit Protection) functions are included. It is available in 18-pin SOPW.
