Multiple Linear Power Controller with ACPI Control Interface
The HIP6503 complements either an HIP6020 or an
HIP6021 in ACPI-compliant designs for microprocessor and
computer applications. The IC integrates four linear
controllers/regulators, switching, monitoring and control
functions into a 20 pin SOIC package. One linear controller
generates the 3.3V
DUAL
/3.3V
SB
voltage plane from the ATX
supply’s 5VSB output, powering the south bridge and the
PCI slots through an external pass transistor during sleep
states (S3, S4/S5). A second transistor is used to switch in
the ATX 3.3V output for operation during S0 and S1/S2
(active) operating states. A linear controllers/regulator
supplies at choice either of 2.5V or 3.3V memory power
through external pass transistors (switch for 3.3V setting) in
active states. During sleep states, integrated pass
transistors supply the sleep power. Another controller
powers up the 5V
DUAL
plane by switching in the ATX 5V
output in active states, and the ATX 5VSB in sleep states.
Two internal regulators output both a dedicated, noise-free
2.5V clock chip supply, as well as a 1.8V ICH2 resume well
voltage. The HIP6503’s operating mode (active outputs or
sleep outputs) is selectable through two digital control pins,
S3 and S5. Enabling sleep state support on the 5V
DUAL
output is offered through the EN5VDL pin. In active state, the
3.3V
DUAL
/3.3V
SB
and 2.5V
MEM
/3.3V
MEM
linear regulators
use external N-channel pass MOSFETs to connect the
outputs directly to the 3.3V input supplied by an ATX power
supply, for minimal losses. In sleep state, power delivery on
both outputs is transferred to NPN transistors. Active state
regulation on the 2.5V
MEM
output is performed through an
external NPN transistor. The 5V
DUAL
output is powered
through two external MOS transistors. In sleep states, a
PMOS (or PNP) transistor conducts the current from the ATX
5VSB output; while in active state, current flow is transferred
to an NMOS transistor connected to the ATX 5V output. The
operation of the 5V
DUAL
output is dictated not only by the
status of the S3 and S5 pins, but that of the EN5VDL pin as
well. The 3.3V
DUAL
/3.3V
SB
and 1.8V
SB
outputs are active
for as long as the ATX 5VSB voltage is applied to the chip.
The 2.5V
CLK
output is only active during S0 and S1/S2, and
uses the 3V3 pin as input source for its internal pass
element.
