LP3350–00 Version 0.3 NOV-2017

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

available in a space saving SOP-8 (0.5mm pitch)

package.
