Preliminary Datasheet

LP3100

Dual Channel Charge Pump Power Solution For TFT LCD Panel

General Description

The LP3100 DC/DC converter integrates two low

noise, high efficiency charge pumps for dual outputs,

which consist of one inverting output and a step-up

output. The device operates from 2.5V to 4.8V input,

and provides a step-up output voltage (VP) of 2x the

input voltage. The negative inverting output (VN) is

-1xinverted from the positive output VP.

The LP3100 is available in a small TDFN-12 pin

package that features a bottom side exposed

thermal pad to provide optimal heat dissipation. The

small package size and low external parts count

make the device ideally suitable for TFT LCD

applications of mobile products. The device is rated

to operate from – 40 ℃ to +85 ℃ ambient

temperature range.
