MP1011A

Cold Cathode Fluorescent Lamp Driver

General Description

Features

The MP1011A is a Power IC offering a

complete solution for driving one or more

Cold Cathode Fluorescent Lamps (CCFL).

This Power IC converts unregulated DC voltage

to a nearly pure sine wave required to ignite and

operate the CCFL. Based on proprietary power

topology and patented control techniques, it

greatly increases the power conversion

efficiency. The MP1011A supports both analog

and burst mode dimming without any additional

external components. The MP1011A offers four

distinct performance advantages:

Integrated power switches

6.0 to 22v variable supply voltage with

regulated lamp current.

Rated 12W power output at 12V input

Open lamp regulation

Current and Voltage feedback control

Logic Level burst mode control

Thermal Shutdown

Supports Open/Short Lamp protection

Soft Start

Output is short circuit protected

Low lamp operating voltage for increasing

transformer or using smaller transformer

Allows Burst-Mode Operation

No ballast capacitor required

1. More light for less power

2. Small board implementation

3. Low EMI emission

4. Low cost off the shelf components
