Functional Pin Description
5VSBY (Pin 1)
5VSBY is the bias supply of the ISL6548A. It is typically
connected to the 5V standby rail of an ATX power supply.
During S4/S5 sleep states the ISL6548A enters a reduced
power mode and draws less than 1mA (I
CC_S5
) from the
5VSBY supply. The supply to 5VSBY should be locally
bypassed using a 0.1
μ
F capacitor.
P12V (Pin 3)
The V
TT
regulation circuit and the Linear Drivers are
powered by P12V. P12V is not required during S3/S4/S5
operation. P12V is typically connected to the +12V rail of an
ATX power supply.
GND (Pins 4, 27, 29)
The GND terminals of the ISL6548A provide the return path
for the V
TT
LDO, and switching MOSFET gate drivers. High
ground currents are conducted directly through the exposed
paddle of the QFN package which must be electrically
connected to the ground plane through a path as low in
inductance as possible.
