The DiodesZetex AL3353 is a highly-integrated and cost-effective LED controller optimized for LCD monitor and LCD TV backlighting application. It provides a high-performance LED backlight solution with low-BOM cost. The AL3353 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. It offers PWM-to-analog dimming mode for a wide range of dimming control.

Wide input voltage range of 9V to 40V high precision feedback reference voltage of 400mV/±1.5% current mode PWM controller with good dynamic response PWM to analog dimming mode with built-In comprehensive protections
