Multiple Linear Power Controller with
ACPI Control Interface
The ISL6506 complements other power building blocks
(voltage regulators) in ACPI-compliant designs for
microprocessor and computer applications. The IC
integrates the control of the 5V
an 8 pin EPAD SOIC package. The ISL6506 operating mode
(active outputs or sleep outputs) is selectable through two
digital control pins, S3# and S5#.
A completely integrated linear regulator generates the
3.3V
during sleep states (S3, S4/S5). In active states (during S0
and S1/S2), the ISL6506 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.
The ISL6506 powers up the 5V
the ATX 5V output through an NMOS transistor in active
states, or by switching in the ATX 5V
PNP) transistor in S3 sleep state. In S4/S5 sleep states, the
ISL6506 and ISL6506B 5V
ISL6506A, the 5V
states.
Functionally, the ISL6506 and ISL6506B are identical. The
ISL6506B, however, features a 2A current limit on the
internal 3.3V LDO while the ISL6506 has a 1A current limit.
The ISL6506A has a 1A current limit on the internal 3.3V
LDO.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
