EL7581
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-pin HTSSOP 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 is 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-020B.
