EUP2681 Datasheet Tft Lcd DC-dc Converter

Manufacturer: Eutech Microelectronics

Overview: EUP2681 TFT LCD DC-DC Converter with Integrated Charge Pumps, OP-AMP and.

General 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.

The device integrates a step-up converter, positive and negative charge pumps, a high speed V buffer and a HV-Switch.

The external pensated step-up converter

Key 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.
