MP3388  
50V, 8-String White LED Driver  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP3388 is a step-up converter with  
8-channel current sources designed for driving  
the white LED arrays for large size LCD panel  
backlighting applications.  
High Efficiency and Small Size  
4.5V to 25V Input Voltage Range  
50V Maximum Step-up Voltage  
Balanced Driver for 8 Strings of WLED  
3% Current Matching Accuracy Between  
Strings  
Selectable Switching Frequency: 1.25MHz or  
625kHz  
PWM or DC Input Burst PWM Dimming  
Programmable Over-voltage Protection  
Under Voltage Lockout  
The MP3388 uses current mode, fixed frequency  
architecture. The switching frequency can be  
selected at 1.25MHz or 625kHz. It generates an  
output voltage up to 50V from a 4.5V to 25V input  
supply. The MP3388 independently regulates the  
current in each LED string to the user programmed  
value set by an external current setting resistor.  
Open and Short LED protection  
Thermal Shutdown  
Small 24-pin QFN (4mm x 4mm) and 28 pin  
SOIC packages  
The MP3388 applies 8 internal current sources in  
each LED string terminal to achieve a current  
balance of 3% regulation accuracy between  
strings. Its low 600mV regulation voltage on LED  
current sources reduces power loss and improves  
efficiency.  
Halogens Free  
APPLICATIONS  
The MP3388 features external PWM dimming or  
DC input PWM dimming, which allows the flexible  
control of the backlighting luminance. The dimming  
PWM signal can be generated internally, and the  
dimming frequency is programmed by an external  
setting capacitor.
