MP3398A

Step up, 4 strings, Max. 350mA/string

Analog and PWM dimming, White LED Controller

DESCRIPTION

FEATURES

The MP3398A is a step-up controller with 4

current channels, which is designed to drive

WLED arrays for large-size LCD-panel

backlighting applications. It is flexible to expand

the number of LED channels by two or more

ICs in parallel sharing a single inductive power

source.



4-String, Max 350mA/String WLED Driver

5V to 28V Input Voltage Range

2.5% Current Matching Accuracy Between

Strings



Programmable Switching Frequency

PWM and Analog Dimming Mode

Cascading Capability with a Single Power

Source

The MP3398A uses peak-current mode with

fixed switching frequency. The frequency is

programmable by an external setting resistor.

The MP3398A drives an external MOSFET to

boost up the output voltage from a 5V to 28V

input supply. It regulates the current in each

LED string to the value set by an external

current-setting resistor.



LED Open and Short LED Protection

Programmable Over-Voltage Protection

Recoverable Thermal Shutdown Protection

Over Current Protection

Inductor/Diode short Protection

Under-Voltage Lockout

SOIC16, TSSOP16-EP and SOIC20

Packages

The MP3398A 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.

APPLICATIONS



Desktop LCD Flat Panel Displays

Flat Panel Video Displays

2D/3D LCD TVs and Monitors

The MP3398A can support both analog and

PWM dimming independently to meet the

different dimming-mode request. In addition,

rich protection modes are also integrated

including OCP, OTP, UVP, OVP, LED

short/open protection, inductor/diode short

protection.

All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For

MPS green status, please visit MPS website under Quality Assurance.
