Preliminary Datasheet

LP3102

Dual Channel Charge Pump Power Solution For TFT LCD Panel

General Description

The LP3102 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 -1x

inverted from the positive output VP.

The LP3102 is available in a small TDFN-10 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.
