FN9109.3
Multiple Linear Power Controller with
ACPI Control Interface
The ISL6505 complements 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 20-pin wide-body
SOIC or 20-pin QFN (also known as MLF) 5x5 package.
The ISL6505’s operating mode (active or sleep outputs) is
selectable through two digital control pins, S3 and S5.
One linear controller generates the 3.3V DUAL /3.3V SB
voltage plane from the ATX supply’s 5V SB output, powering
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 DUAL /3.3V SB linear
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. The 3.3V DUAL /3.3V SB
output is active for as long as the ATX 5V SB voltage is applied
to the chip.
A controller powers up the 5V DUAL plane by switching in the
ATX 5V output through an NMOS transistor in active states,
or by switching in the ATX 5V SB through a PMOS (or PNP)
transistor in S3 sleep state. In S4/S5 sleep states, the

PACKAGE
DWG. #
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.

and 1.5V, using an external resistor divider. The mode is
user-selectable with the LAN pin; a logic high (or open)
selects the 10/100 LAN mode, where V OUT1 is always on
(S0-S5); a logic low selects the Gigabit Ethernet mode,
where V OUT1 is only on during active modes (S0-S2).

NOTE:
1. Intersil Pb-free plus anneal 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.
