ISL6505
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
ISL6505 5V
DUAL
output is either shut down or stays on,
based on the state of the EN5 pin.
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.
A linear controller generates V
OUT1
from the
3.3V
DUAL
/3.3V
SB
voltage plane, using an external NFET.
The voltage is user-programmable to values between 1.2V
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 Lead-Free products employ special lead-free material sets;
molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
lead-free soldering operations. Intersil Lead-Free products are
MSL classified at lead-free peak reflow temperatures that meet or
exceed the lead-free requirements of IPC/JEDEC J Std-020B.
