3-Channel DC/DC Converter

Features

• TFT/LCD display supply

- Boost regulator

The EL7581 is a 3-channel DC/DC converter IC which is

designed primarily for use in TFT/LCD applications. It

features a PWM boost converter with 2.7V to 14V input

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

drivers and provides up to 720mA @12V, 570mA @ 15V

from 5V input. A pair of charge pump control circuits provide

and -5V to -40V, respectively, each at up to 60mA.

< 40V

The EL7581 features adjustable switching frequency,

adjustable soft start, and a separate output V

control to allow selection of supply start-up sequence. An

over-temperature feature is provided to allow the IC to be

automatically protected from excessive power dissipation.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
