LP6286–00 Version 0.0 NOV.-2016

Multi-Channel DC-DC Converter for LCD Panel

General Description

The

LP6286

includes

a

high-efficiency

boost

regulator, a gate pulse modulator (GPM), a voltage

detector, a VCOM buffer, and dual charge pump

controller for active matrix TFT LCDs.

The

converter

is

a

high

switching

frequency

current-mode

regulator

with

an

integrated

N-

Channel 0.2Ω MOSFET that allows the use of

small inductors and ceramic capacitors.

The OPA can drive the LCD VCOM voltage by

outputs.

The charge pump controller provides regulated TFT

Gate-On voltage. The regulation of the charge pump

is generated by the internal comparator that senses

the output voltage and compares it with an internal

reference.

Other features include under-voltage protection,

short circuit protection, thermal shutdown protection

and under-voltage lockout (UVLO). The

available in a space saving QFN-24 (0.5mm pitch)

package.
