EL7585
FN7345.2
TFT-LCD Power Supply
The EL7585 represents a multiple output regulators for use
in all large panel, TFT-LCD applications. It features a single
boost converter with integrated 3.5A FET, two positive LDOs
for VON and VLOGIC generation, and a single negative LDO
for VOFF generation. The boost converter can be
programmed to operate in either P-mode or PI-mode for
improved load regulation.
The EL7585 also integrates fault protection for all four
channels. Once a fault is detected, the device is latched off
until the input supply or EN is cycled. This device also
features an integrated start-up sequence for VBOOST, VOFF,
then VON or for VOFF, VBOOST, and VON sequencing. The
latter requires a single external transistor. The timing of the
start-up sequence is set using an external capacitor.
The EL7585 is specified for operation over the -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.
