3-Channel DC/DC Converter
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
regulated outputs of V ON and V OFF supplies at 8V to 40V
and -5V to -40V, respectively, each at up to 60mA.
The EL7581 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 EL7581 is available in a 20 Ld HTSSOP package and is
specified for operation over the full -40°C to +85°C
temperature range.

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.
