7.3.1 Fan Connector Electrical Characteristics
The fan connector supply pin is supported by a buck switching regulator that is set to limit the fan supply voltage at
approximately 12V. The maximum duty cycle of the regulator is 90%, so the maximum output of the regulator will be
approximately 90% of the supply voltage input to the regulator.
CAUTION:
Be aware of the wide range of input voltages and acceptable fan voltages and ensure that the fan you
select supports the applied voltage.
The maximum current supported on that output is 125mA @ 60°C ambient because it is current limited by a
resettable fuse.
