Functional Pin Description
5VSBY (Pin 1)
5VSBY is the bias supply of the ISL6537A. It is typically
connected to the 5V standby rail of an ATX power supply.
During S4/S5 sleep states the ISL6537A 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.
6
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 ISL6537A provide the return path
for the V TT LDO, and switching MOSFET gate drivers. High
