OB3362F

4 Channels High Performance LED Driver

FEATURES

GENERAL DESCRIPTION

10V gate drive, better MOS compatibility

High Efficiency and Compact Size

6V to 30V Input Voltage Range

The OB3362F is a highly integrated and high

performance LED driver that optimized for LCD

backlight application. It integrates a boost driver

and 4 channels of current balancer that optimized

to drives multi LED arrays, and thus provides a

high performance LED backlight solution with

minimized BOM count.

3% Matching Accuracy Between 4 LED

Strings Control Current

100KHz~600KHz Operating Frequency

Internal/External PWM Dimming

Very Low Standby Power

The OB3362F contains a PWM boost driver which

uses current mode control and fixed frequency

operation. The operation frequency can be

programmed by setting external resistor value at

RI pin.

Programmable Over Voltage Protection

Under Voltage Lockout(UVLO)

Open/Short LED Protection

The OB3362F integrates 4 channels current

balancer with up to 200mA current capability per

channel and it can achieve 3% matching accuracy

among LED strings. The minimum voltage of

current source is regulated to as lower as 350mV,

which benefits the efficiency and improves the IC

thermal performance.

Thermal Shutdown

APPLICATIONS

LCD Monitor

LCD TV

The OB3362F supports external PWM dimming

and internal burst dimming mode which allow

flexible control of the backlight luminance. The

LED current is directly modulated by external

PWM duty cycle when PWM dimming mode is

selected. The LED current can be adjusted by an

external DC voltage when internal burst dimming

mode is selected.

Flat panel display

OB3362F is offered in 16-pin ESOP/DIP
