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.

Monolithic Power Systems, Inc.

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.
