Introduction
The LT3513 is a highly integrated,
5-output regulator designed to provide all the supply voltages typically
required by large TFT liquid crystal
displays (LCDs) with a single IC. The
part features a step-down switching
regulator to produce a 3.3V or 5V
logic voltage from a wide voltage range
input, such as automotive battery.
A lower voltage logic supply can be
generated from the first supply by
adding an external NPN driven by an
internal linear regulator. The other
three on-chip regulators provide the
three bias voltages required by LCDs: a
high power boost regulator to generate
AVDD, a low power boost regulator to
generate VON and an inverting regulator to provide VOFF. …
