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 (ICC_S5) from the
5VSBY supply. The supply to 5VSBY should be locally
bypassed using a 0.1
μF capacitor.
P12V (Pin 3)
The VTT 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 VTT LDO, and switching MOSFET gate drivers. High
