EUP2619 Description
The EUP2619 generates power supply rails for thin-film transistor (TFT) liquid-crystal display (LCD) panels in tablet PCs and notebooks operated from 2.5V to 5.5V input supply. The device integrates a step-up converter, positive and negative charge pumps, and a high speed V buffer. The external pensated step-up converter, providing the regulated supply voltage for the panel source driver ICs,.
