Full System Precision CCFL Driver MP1015

General Description
The MP1015 is a Power IC that offers a true complete solution for driving a 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 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:
1. More light for less power
2. Smallest board implementation possible
3. Low EMI emission
4. Low cost off the shelf components

Features

- 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
- No High Voltage Ballast Capacitor
- Evaluation Board Available

Brightness Control
The MP1015 can operate in three modes: Analog Mode, Burst Mode with a DC input, or Burst Mode
with an external PWM. The three modes are dependent on the pin connections as per Table 1.
Choosing the required burst repetition frequency can be achieved by an RC combination, as defined
in component selection. The MP1015 has a soft on and soft off feature to reduce noise, when using
burst mode dimming.
