FN9062.2

Multiple Linear Power Controller with

ACPI Control Interface

Features

• Provides four ACPI-Controlled Voltages

- 5V

DUAL

USB/Keyboard/Mouse

The ISL6504 and ISL6504A complement other power

building blocks (voltage regulators) in ACPI-compliant

designs for microprocessor and computer applications. The

IC integrates three linear controllers/regulators, switching,

monitoring and control functions into a 16-pin wide-body

SOIC or 20-pin QFN 6x6 package. The ISL6504, ISL6504A

operating mode (active outputs or sleep outputs) is

selectable through two digital control pins, S3 and S5.

- 1.5V ICH4 Resume Well

• Excellent Output Voltage Regulation

- All Outputs: ±2.0% over temperature (as applicable)

• Small Size; Very Low External Component Count

• Undervoltage Monitoring of All Outputs with Centralized

FAULT Reporting and Temperature Shutdown

One linear controller generates the 3.3V

voltage plane from the ATX supply’s 5V output, powering

the south bridge and the PCI slots through an external NPN

pass transistor during sleep states (S3, S4/S5). In active

• QFN Package:

- Near Chip Scale Package Footprint; Improved PCB

state (during S0 and S1/S2), the 3.3V

DUAL

regulator uses an external N-channel pass MOSFET to

connect the outputs directly to the 3.3V input supplied by an

ATX power supply, for minimal losses.

• Pb-Free Available (RoHS Compliant)

Applications

A controller powers up the 5V

plane by switching in the

output is shut down. In the ISL6504A, the

DUAL

output stays on during S4/S5 sleep states. This is

DUAL

the only difference between the two parts; see Table 1.

An internal linear regulator supplies the 1.2V for the voltage

identification circuitry (VID) only during active states (S0 and

S1/S2), and uses the 3V3 pin as input source for its internal

pass element. Another internal regulator outputs a 1.5V

chip-set standby supply, which uses the 3V3DL pin as input

source for its internal pass element. The 3.3V /3.3V

DUAL SB

and 1.5V outputs are active for as long as the ATX 5V

voltage is applied to the chip.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
