MP3397

Step-Up, 4-String

Max 350mA/String White LED Driver

The Future of Analog IC Technology

DESCRIPTION

FEATURES



4-String, Max 350mA/String at 10% D_PWM

5V to 28V Input Voltage Range

2.5% Current Matching Accuracy Between

Strings

The MP3397 is a step-up controller with 4

current channels designed to drive WLED

arrays for large-size LCD-panel backlighting

applications. The MP3397 is flexible, and can

expand the number of LED channels with two

or more MP3397s in parallel operating from a

single inductive power source.



Programmable Switching Frequency

PWM or DC Input Burst PWM Dimming

Open and Short LED Protection

Programmable Over-Voltage Protection

Cascading Capability with a Single Power

Source

The MP3397 uses current-mode fixed-

frequency architecture. An external resistor sets

the switching frequency. This signal drives an

external MOSFET to boost up the output

voltage from 5V to a 28V input supply. The

MP3397 regulates the current in each LED

string to the programmed value set by an

external current-setting resistor.



Under-Voltage Lockout

Thermal Shutdown

16-pin TSSOP，SOIC Package

APPLICATIONS



Desktop LCD Flat Panel Displays

Flat Panel Video Displays

2D/3D LCD TVs and Monitors

The MP3397 applies 4 internal current sources

for current balance. The current matching can

achieve 2.5% regulation accuracy between

strings. Its low regulation voltage on LED

current sources reduces power loss and

improves efficiency.

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.

An external PWM input signal or DC input

signal controls PWM dimming. The dimming

PWM signal can be generated internally and

the dimming frequency is programmed by an

external setting capacitor.
