Overview

OB3350 Cost Effective LED Controller GENERAL DESCRIPTION OB3350 is a highly integrated and cost effective Light Emitting Diode (LED) driver optimized for LCD monitor and LCD TV backlighting application.
It provides a high performance LED backlight solution with minimized BOM count.
The OB3350 contains a PWM boost driver which uses current mode control and fixed frequency operation to regulate the LED current.
The LED current is sensed through an external current sense resistor.
The voltage across the sensing resistor is compared with reference level of 300mV, the error is amplified to control the pulse width of the power switch thus to regulate the current flowing the LED.
The OB3350 offers...
