Detailed Description
The AL3353 is a highly integrated and cost effective Light Emitting Diode (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.
The AL3353 offers PWM to analog dimming mode for a wide range of dimming control.
The AL3353 has comprehensive protection features and it is available in the SO-8 package.
