Description: Cost Effective LED Controller OB3350 G ENERAL DESCRIPTION OB3350 is a highly i ntegrated and cost effective Light Emit ting Diode (LED) driver optimized for L CD monitor and LCD TV backlighting appl ication. It provides a high performance LED backlight solution with minimized BOM count. The OB3350 contains a PWM bo ost driver which uses current mode cont rol and fixed frequency operation to re gulate the LED current. The LED current is sensed through an external current sense resistor. The voltage across the sensing resistor is compared with refer ence level of 300mV, the error is ampli fied to control the pulse width of the power switch thus to regulate the curre nt flowing the LED. The OB3350 offer
