LED Driver with PWM Dimming Control



General Description

LP3350 is a cost effective LED driver optimized for LCD monitor and LCD TV backlighting application. It provides a high performance LED backlight solution with minimized bill of material count. The LP3350 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 0.3V, the error amplified to control the pulse width of the power switch thus to regulate the current flowing the LED. Otherwise, The LP3350 offers external frequency PWM dimming method for a wide range of dimming control. Other features include over current protection (OCP), output over voltage protection (OVP), and under-voltage lockout (UVLO). The LP3350 is available in a space saving SOP-8 (0.5mm pitch) package.
