MP3388S

50V, 8-String, Step-Up, White LED Driver

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP3388S is a step-up converter with 8

current-source channels designed to drive arrays

of white LED for LCD-panel backlighting

applications.



High Efficiency

Compact Size

4.3V-to-25V Input Voltage Range

50V Maximum Step-Up Voltage

Balanced Driver for 8 WLED Strings

2.5% Current-Matching Accuracy between

Strings

Selectable Switching Frequency of 625kHz

or 1.25MHz

PWM or DC Input-Burst PWM Dimming

Programmable Over-Voltage Protection

Under-Voltage Lockout

The

MP3388S

uses

current-mode,

fixed-frequency architecture, and users can select

a switching frequency of either 625kHz or

1.25MHz. It generates an output voltage up to

50V from a 4.3V-to-25V input supply. The

MP3388S independently regulates the current in

each LED string set by an external current setting

resistor to a user-programmed value.



Open- and Short-LED Protection

Thermal Shutdown

Small QFN24 (4mm × 4mm) Package

The MP3388S applies an internal current source

to each LED string terminal, and can achieve a

current balance of 2.5% regulation accuracy

between strings. Its low 600mV regulation voltage

on LED current sources reduces power loss and

improves efficiency.

APPLICATIONS



Notebook PCs

Tablet Computers

Small LCD TV

Handheld Terminal Displays

Automotive Electronics Equipments

The MP3388S features external PWM dimming or

DC-input PWM dimming, which allows for flexible

backlight luminance control. The dimming PWM

signal can be generated internally, and the

dimming frequency is programmed by an external

setting capacitor.

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