Data Sheet
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
and 3.3V
DUAL
an 8 Ld 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
voltage plane from the ATX supply’s 5V
DUAL
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
plane by switching in
DUAL
the ATX 5V output through an NMOS transistor in active
states, or by switching in the ATX 5V
SB
PNP) transistor in S3 sleep state. In S4/S5 sleep states, the
ISL6506 and ISL6506B 5V
output is shut down. In the
DUAL
ISL6506A, the 5V
output stays on during S4/S5 sleep
DUAL
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.

NOTES:
1. Add “-T” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is 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.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL6506, ISL6506A, ISL6506B. For more information on MSL please see
techbrief TB363.
