LP3350SOF Overview

LCD TV display backlight IC TV board

Preliminary Datasheet
LP3350
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.
