EUP2644 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 V buffer, a 400mA low dropout (LDO) linear regulator, and a Gate Pulse Modulator (GPM). The external pensated step up converter.
