Input Signals
PSON
Active LOW signal which enables/disables the main output. Pulling this signal LOW will turn-on the main output.
MIN MAX
V
IL
Input logic level LOW 0.8 V
V
IH
Input logic level HIGH 2.0 V 3.46 V
I
SOURCE
Current that may be sourced by this pin 2 mA
I
SINK
Current that may be sunk by this pin at low state 0.5 mA
FAN_POWER
Supplies the fan voltage to the power supply. These pins should be tied to the main 12V output at the system side.
MIN MAX
I
SINK
Current that may be sinked by this pin 3.0 A
Output Signals
ACOK
Signal used to indicate the presence of AC input to the power supply. A logic level HIGH will indicate that the AC input to the power
supply is within the operating range while a logic level LOW will indicate that AC has been lost.
MIN MAX
V
IL
Input logic level LOW 0.6 V
V
IH
Input logic level HIGH 2.0 V 3.3 V
I
SOURCE
Current that may be sourced by this pin 3.3 mA
I
SINK
Current that may be sunk by this pin at low state 0.7 mA
PWR_GOOD / PWOK
“Signal used to indicate that main output voltage is within regulation range. The PWR_GOOD signal will be driven HIGH when the output
voltage is valid and will be driven LOW when the output falls below the under-voltage threshold.
This signal also gives an advance warning when there is an impending power loss due to loss of AC input or system shutdown request.
