500mA Dual Linear Regulator with V_AUXDriver

FEATURES

DESCRIPTION

Continuous 3.3V output from three inputs

The SS6532 is a dual-input regulator with V

AUX

Complete power management solution

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

, V

regulator supplies 500mA output

SBY

Built-in hysteresis when selecting input supplies

Drive control signal for external V switch

AUX

Output can be forced higher than input (off-state)

using the following order: V , V

, and V

CC SBY

AUX

The SS6532 meets Intel's "Instantly Available"

power requirements which follow the ACPI

"Advanced Configuration and Power Interface"

standards.

APPLICATIONS

Desktop Computers

PCI Adapter Cards with Wake-on-LAN

Network Interface Cards (NICs)

Multi-power Systems

When either V or V

is present, the device

SBY

automatically enables the regulator and produces

a stable 3.3V output. When only V (3.3V) is

Systems with Standby Capabilities

AUX

present, the drive control output will turn on an

external P-MOSFET switch from an auxiliary

3.3V supply V

to maintain V

AUX

OUT

The IC also prevents excessive current from

flowing back from V to either input or ground

OUT

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.
