EUP2619 Datasheet (Eutech Microelectronics)

EUP2619, TFT LCD DC-DC Converter

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 VCOM buffer.

* 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 2.8A peak current limit for the internal switch
