Full System

Precision CCFL Driver

Monolithic Power Systems

General Description

Features

The MP1015 is a Power IC that offers a true

complete solution for driving a Cold Cathode

ꢀ

Built-in Burst Mode Oscillator and Modulator

Built-in Analog and Burst Mode Dimming

Built-in Current and Voltage Feedback Control

Built-in Open/Short Lamp Protection

Built-in Dual Mode Fault Timer

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 control

techniques (patented), it greatly increases the

power conversion efficiency. The MP1015 can be

used with analog or burst mode dimming without

any additional external components. The MP1015

offers four distinct performance advantages:

Built-in Soft-on/Soft-off Burst Mode

Automatic Recovery from ESD Event

Wide Range 6 to 22V Battery Voltage with

Regulated Lamp Current

ꢀ

Startup at all voltages and temp without

additional components

ꢀ

Integrated 0.10Ω Power Switches

Output Short Circuit Protected

1. More light for less power

2. Smallest board implementation possible

3. Low EMI emission

No High Voltage Ballast Capacitor

Evaluation Board Available

4. Low cost off the shelf components
