Multiple Linear Power Controller with
ACPI Control Interface
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.
One linear controller generates the 3.3V
voltage plane from the ATX supply’s 5V
the south bridge and the PCI slots through an external NPN
pass transistor during sleep states (S3, S4/S5). In active
state (during S0 and S1/S2), the 3.3V
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.
A controller powers up the 5V
ATX 5V output through an NMOS transistor in active states,
or by switching in the ATX 5V
transistor in S3 sleep state. In S4/S5 sleep states, the
ISL6504 5V

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
and 1.5V
voltage is applied to the chip.
