EL7585/EL7585A pdf datasheet (

The EL7585A 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 EL7585A 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
VLOGIC output is constantly enabled, but does shut down
when a fault condition is detected.
The EL7585A is specified for operation over the -40¡ãC to
+85¡ãC temperature range.
