TFT-LCD Power Supply
The EL7586 and EL7586A represent multiple output
regulators for use in all large panel, TFT-LCD applications.
Both feature a single boost converter with an integrated 2A
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.
Both EL7586 and EL7586A also integrate fault protection for
all four channels. Once a fault is detected, the device is
latched off until the input supply or EN is cycled. EL7586
also features an integrated start-up sequence for
VBOOST/VLOGIC, VOFF, then VON or for VLOGIC, VOFF,
VBOOST, and VON. The latter requires a single external
transistor. The timing of the start-up sequence is set using
an external capacitor.
EL7586A features an immediately-enabled VLOGIC output
which is independent of EN input. The VLOGIC output will be
switched off if a fault is detected and the power supply needs
to be recycled to reset this condition.
Both the EL7586 and EL7586A are pin-compatible, come in
the 20 Ld 4x4 QFN package, and are 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.
