MP1039  
Full Bridge  
CCFL Controller  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP1039 is a fixed operating frequency  
inverter controller that controls four external  
N-Channel power MOSFETs in a full-bridge  
configuration. The inverter is designed to power  
one or more cold cathode fluorescent lamps  
(CCFL) to backlight liquid crystal displays. Its  
full-bridge architecture converts unregulated DC  
input voltages to the nearly pure sine waves  
required to ignite and operate CCFL.  
•
Drives Four External, Low Cost, N-Channel  
MOSFETs  
Programmable Fixed Operating Frequency  
Input Voltage Range of 10V to 28V  
Lamp Current and Voltage Regulation  
Full-Wave Sense Amp  
Analog and Burst Mode Dimming Control  
Integrated Burst Mode Oscillator and Modulator  
Soft-On and Soft-Off Burst Envelope  
Open Lamp Protection  
Secondary Over-Current Protection  
Dual-mode, Fault Timer

The switching frequency is set by an external  
resistor, and can be synchronized to an external  
clock to minimize the potential video display  
interference. The built-in burst oscillator can be  
synchronized with an external clock to minimize  
display scan interference. Burst mode or analog  
mode dimming is controlled with an external  
analog signal. Built-in fault management features  
include an open lamp regulator, a transformer  
secondary peak current regulator, and a dual-  
mode fault timer. The secondary over-current  
timeout can be shortened with external  
components. The MP1039 is available in  
TSSOP28 and SOIC28 packages.  
Drives up to 20 Lamps  
Synchronization Ability for both Switching  
Frequency and Burst Frequency  
Available in TSSOP28 and SOIC28 Packages
