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

HV-Switch.

The external compensated step-up converter 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.

The high speed V

current, 20MHz bandwidth, fast slew rate 45V/µs, and

rail-to-rail inputs and outputs.

The HV-Switch circuit control provides the ability to

control the slope for the gate drive voltage. It shapes the

TFT gate high voltage to improve image quality.

The EUP2681 is available in a small (4mm× 4mm) 24 pin

TQFN package and operates over the -40ºC to +85ºC

temperature range.
