EUP2644 Datasheet (Eutech Microelectronics)

EUP2644, TFT LCD DC-DC Converter

The EUP2644 generates power supply rails for thin-film transistor (TFT) liquid-crystal display (LCD) panels in monitors and notebooks operation from 3V to 5.5V input supply.

The device integrates a step-up converter, a high speed VCOM buffer, a 400mA low dropout (LDO) linear regulator, and a Gate Pu

EUP2644 Features

* an internal power MOSFET and high frequency operation allowing the use of small inductors and capacitors. The step up converter uses fixed-frequency, current mode control architecture which provides fast load-transient response and easy compensation. A 2.9A peak current limit for the internal switch
