LP3352 Version 0.2 AUG-2018

6-Channel LED Driver for Backlights

General Description

LP3352 is a cost effective LED driver optimized for

media size LCD backlighting application. It provides

a high performance LED backlight solution with

minimized bill of material count.

LP3352 have a high

performance boost converter

with integrated 2.5A/40V power MOS. The boost

structure which uses current mode control and fixed

frequency operation to regulate the LED current. The

6-CH sink current can be adjusted through an

external resistor. In addition, the LP3352 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 QFN-16 (0.5mm pitch)

package.
