LP3102
Dual Channel Charge Pump Power Solution For TFT LCD Panel
概述
The LP3100SA DC/DC converter integrates two lownoise, 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 LP3100SA 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.
