LP3102QVF

Preliminary Datasheet LP3102 Dual Channel Charge Pump Power Solution For TFT LCD Panel General Description Features The LP3102 DC/DC converter integrates two low  Ultra-Low-Noise for RF Application noise, high efficiency charge pumps for dual outputs,  2.5V to 4.8V Input Supply Voltage Range which consist of one inverting output and a step-up  Adaptive 1.5x / 2x mode switchover for positive voltage and -1x mode for negative voltage  VP output range (VOUT ≦ 2x VIN): 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 5.5V to 5.9V (LP3102QVF) VN output range (VOUT ≦ 2x VIN):  -5.5V to -5.9V (LP3102QVF)  High current output: Vin=3.3V, IOUT=±120mA;  Built in Power On Sequence  TDFN-10 (3.0mm × 3.0mm) Package device ideally suitable for TFT LCD applications of mobile products. The device is rated to operate from -40℃ to +85℃ ambient temperature range.
