DESCRIPTION
The SS6532 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.
The SS6532 meets Intel's "Instantly Available"
power requirements which follow the ACPI
"Advanced Configuration and Power Interface"
standards.
When either VCC or VSBY is present, the device
automatically enables the regulator and produces
a stable 3.3V output. When only VAUX (3.3V) is
present, the drive control output will turn on an
external P-MOSFET switch from an auxiliary
3.3V supply VAUX to maintain VOUT.
The IC also prevents excessive current from
flowing back from VOUT to either input or ground
when the output voltage is greater than the input
voltage.
All the control circuitry needed to provide a
a smooth and automatic transition between all
three supplies has been incorporated. This allows
both VCC and VSBY to be dynamically switched
without loss of output voltage.
