MP3389  
12–String, Step-up  
White LED Driver  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
•
•
•
•
•
High Efficiency and Small Size  
The MP3389 is a step-up controller with 12-  
channel current sources designed for driving  
the WLED arrays for large size LCD panel  
backlighting applications.  
5V to 28V Input Voltage Range  
Balanced Driver for 12 Strings of WLEDs  
Maximum 60mA for Each String  
2.5% Current Matching Accuracy Between  
Strings  
The MP3389 uses current mode, fixed frequency  
architecture. The switching frequency is  
programmable by an external frequency setting  
resistor. It drives an external MOSFET to boost  
up the output voltage from a 5V to 28V input  
supply. The MP3389 regulates the current in  
each LED string to the programmed value set by  
an external current setting resistor.

Programmable Switching Frequency  
PWM or DC Input Burst PWM Dimming  
Open and Short LED protection  
Programmable Over-voltage Protection  
Under Voltage Lockout  
Thermal Shutdown  
28-pin TSSOP and 28-pin SOIC Package  
The MP3389 applies 12 internal current  
sources for current balance. And the current  
matching can achieve 2.5% regulation accuracy  
between strings. Its low 550mV regulation  
voltage on LED current sources reduces power  
loss and improves efficiency.  
APPLICATIONS  
•

•
Desktop LCD Flat Panel Displays  
Flat Panel Video Displays  
LCD TVs and Monitors  
All MPS parts are lead-free and adhere to the RoHS directive. For MPS green  
status, please visit MPS website under Quality Assurance. “MPS” and “The  
Future of Analog IC Technology” are Registered Trademarks of Monolithic  
Power Systems, Inc.  
PWM dimming is implemented with external  
PWM input signal or DC input signal. The  
dimming PWM signal can be generated internally,  
and the dimming frequency is programmed by  
an external setting capacitor.
