! DESCRIPTION
AIC1532 is a dual input regulator with VAUX drive
control capable of delivering 3.3V/500mA
continuously. The output power is provided from
three independent input voltage sources on a
prioritized basis. Power is always taken in priority
using the following order VCC, VSBY, and VAUX .
AIC1532 meets Intel’s “ Instantly Available ” power
requirements which follows the “Advanced
Configuration and Power Interface“ (ACPI)
standards. When either VCC or VSBY is present, the
device automatically enables the regulator and
produces a stable 3.3V output VOUT. When only
VAUX (3.3V) is present, the drive control output will
turn-on an external PMOS switch from an auxiliary
3.3V supply VAUX to VOUT.
The IC also prevents excessive current from flowing
VOUT to either input voltage or ground when the
output voltage is bigger than the input voltage.
All the necessary control circuitry needed to provide
a smooth and automatic transition between all the
three supplies has been incorporated. This allows
both VCC and VSBY to be dynamically switched
without loss of output voltage.
