Dual Channel Charge Pump Power

Solution For TFT LCD Panel

ELP3100

General Description

The ELP3100 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 2.5 V 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 ELP3100 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 suit able for TFT LCD applications of mobile products . The device is rated to operate

from â 40â to +85â ambient temperature range .
