EL7584

4-Channel DC/DC Converter

DATASHEET

The EL7584 is a 4-channel DC/DC converter IC which is

designed primarily for use in TFT-LCD applications. The

boost converter has 2V to 14V input capability and provides

5V to 17V output, which powers the column drivers and

provides up to 370mA @ 15V. A pair of charge pump control

circuits provide outputs to allow the external generation of

from 2V to 13V.

The EL7584 features adjustable switching frequency and on-

chip power sequence to simplify start-up operation. A

separate input is available to externally increase the default

delay of the positive charge pump. An over-temperature

feature is provided to allow the IC to be automatically

protected from excessive power dissipation.

The EL7584 is available in a 24-pin TSSOP package and is

specified for operation over the full -40°C to +85°C

temperature range.
