EUP2681, TFT LCD DC-DC Converter

EUP2681 TFT LCD DC-DC Converter with Integrated Charge Pumps, OP-AMP and HV-Switch .
The EUP2681 generates power supply rails for thin-film transistor (TFT) liquid-crystal display (LCD) panels in monitors and notebooks operated from 2.

Features

* an internal power MOSFET and high frequency operation allowing to use small inductors and capacitors. The step up converter uses fixed-frequency peak current mode control architecture which provides fast load-transient response and easy compensation. A 3.5A peak current limit for the internal switch
