3-Channel DC/DC Converter

Features

• TFT-LCD display supply

- Boost regulator

The EL7583 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 470mA @ 12V, 370mA @ 15V

from 5V supply. A pair of charge pump control circuits

The EL7583 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 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.
