OB3370N Cost Effective LED Controller GENERAL DESCRIPTION OB3370N is a high integrated and cost effective Light Emitting Diode (LED) driver optimized for LCD monitor and LCD TV backlight application. The OB3370N operates in voltage mode boost topology with fixed frequency 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 200mV, the error is amplified to control the pulse
