Description

To aim at the Cold Cathode Fluorescent Lamp (CCFL) applications, the BIT3102A integrated all functions required in a single 8 pin chip. The chip provides a fully functioned PWM control circuit with a true lamp current feedback protection. By setting the required time for striking the lamp through SST , the open-lamp condition can be detected after lamp striking period. The lamp dimming can be done through a PWM feedback loop. CMOS process reduces the operating current (1mA typical) and NMOS output driving capability enhances the system efficiency.

Features

1. PWM Modulation

2. Open Lamp Protection

3. Internal UVLO (Under Voltage Lock Out) function

4. Dimming Control

5. CMOS Totem Pole output

6. NMOS output driving

Pinouts:

Applications:

1. Cold Cathode Fluorescent Lamps system

2. Notebook PC

3. LCD Monitor

4. Palm-top Computers

5. Video Phone/ Door Phone

6. Portable Instrumentation

7. Personal Digital Assistants
