Description
The EUP2681 generates power supply rails for thin-film transistor (TFT) liquid-crystal display (LCD) panels in monitors and notebooks operated from 2.5V to 5.5V input supply.
Features
- 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 3.5A peak current limit for the internal switch protects power supply fault condition. The regulated positive and negative charge pump regulators generate the positive and negative supply rails for the TFT LCD gate resistive voltage-divider ICs. T.
