MP1048  
Full Bridge  
CCFL Controller  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP1048 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  
up to 6 cold cathode fluorescent lamps (CCFLs)  
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 CCFLs.

Capable of Driving up to 6 Lamps  
Controls Four External, Low Cost, N-Channel  
MOSFETs

Fixed Operating Frequency  
Input Voltage Range of 10V to 22V  
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  
Available in TSSOP28 and SOIC28 Packages  
For reliable lamp ignition, the operating  
frequency is set by an external resistor and  
during startup is temporarily swept toward the  
unloaded resonant frequency of the tank. Burst  
mode or analog mode dimming are 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  
MP1048 is available in TSSOP28 and SOIC28  
packages.
