MP3384

50V, 4-String White LED Driver

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP3384 is a step-up converter with

4-channel current sources designed for driving

the white LED arrays for large size LCD panel

backlighting applications.

•

High Efficiency and Small Size

4.5V to 25V Input Voltage Range

50V Maximum Step-up Voltage

Balanced Driver for 4 Strings of WLED

2.5% Current Matching Accuracy Between

Strings

Selectable Switching Frequency: 1.25MHz or

625kHz

PWM Dimming

Programmable Over-voltage Protection

Under Voltage Lockout

Open and Short LED Protection

Thermal Shutdown

The MP3384 uses current mode, fixed frequency

architecture. The switching frequency can be

selected at 1.25MHz or 625kHz. It generates an

output voltage up to 50V from a 4.5V to 25V input

supply. The MP3384 independently regulates the

current in each LED string to the user programmed

value set by an external current setting resistor.

•

The MP3384 applies 4 internal current sources to

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.

Small 16-pin QFN (3mm x 3mm)

APPLICATIONS

•

Notebook PC

Netbook PC

Digital Picture Frames

Handy Terminals Display

Automotive System and Tablet Computer

The MP3384 includes under voltage lockout,

current limiting, over voltage, short LED, open LED

and thermal shut-down protection.

The MP3384 is available in small QFN16

(3mmx 3mm) package.
