MP3373  
8 Strings, Step Up WLED Controller  
with External Transistor  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP3373 is a step-up controller with 8-  
channel external current sources designed for  
driving the WLED arrays for large size LCD  
panel backlighting applications.  
9V to 40V Input Voltage Range  
8-Channel LED strings with external current  
balance  
1.2% Current Matching Accuracy Between  
Strings  
Programmable Switching Frequency  
External PWM Dimming  
Selectable Phase Shift Function at PWM  
DIM Mode  
The MP3373 employs peak current mode, fixed  
frequency architecture to provide robust operation  
with 9V to 40V input supply. The switching  
frequency is programmable by an external  
frequency setting resistor.  
Open/Short LED Protection  
Short Inductor/Diode Protection  
Programmable Over-voltage Protection  
Thermal Shutdown  
Fault Flag Output  
Extendable LED Channels with Share One  
Set of Power Stage  
The MP3373 integrates the constant current  
control circuit to regulate each LED string current  
to the programmed value set by an external  
resistor. And the current matching can achieve  
1.2% regulation accuracy between strings. Its  
low 200mV regulation voltage on LED current  
sources reduces power loss and improves  
efficiency.  
TSSOP-28 and SOIC-28 Packages  
To reduce inrush current and the stress of  
components, MP3373 employs the phase shift  
PWM dimming mode which can be disabled by  
pulling PSEN pin to GND.  
APPLICATIONS  
LCD Flat Panel Displays  
2D/3D 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 Products, Quality Assurance page.  
MP3373 also includes UVLO, LED short/open  
protection, inductor/diode short protection and  
thermal shut down protection. All these faults are  
indicated by the fault flag signal.

The MP3373 is flexible for extending LED  
channels with two or three ICs in parallel with  
sharing one power stage. It is available in  
TSSOP-28 and SOIC-28 packages.
