Overview

OB3353A 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 OB3353A 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 400mV the error is amplified to control the pulse width of the power switch thus to regulate the current flowing the LED. The OB3353A offers PWM to analog dimming method for a wide range of dimming control. The OB3353A offers comprehensive protection such as power MOSFET over current protection (OCP), output over voltage protection (OVP), Diode & Inductor short protection, LED cathode short to GND protection, IC power supply under voltage lockout (UVLO), and LED open protection.
