EUP2644 Overview
Description
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 Pulse Modulator (GPM).
