EL7583
3-Channel DC/DC Converter
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
provide regulated outputs of V
ON
and V
OFF
supplies at 8V
to 40V and -5V to -40V, respectively, each at up to 60mA.
The EL7583 features adjustable switching frequency,
adjustable soft start, and a separate output V
ON
enable
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.
The EL7583 is available in a 20-pin TSSOP package and is
specified for operation over the full -40°C to +85°C
temperature range.

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.
