Control and Status Signals
Input Signals
PSON_L
Active LOW signal which enables/disables the main output. Pulling this signal LOW will turn-on the main output. System Side pull-up resistor is not required.

0.5 mA
PSKILL_H
First break/last mate active HIGH signal which enables/disables the main output. This signal will have to be pulled to ground at the system side.
MIN
MAX
VIL
VIH
Input logic level LOW. This allows for the power supply to
be tunred on
0.8 V
Input logic level HIGH. Immediately shuts down the power
supply

ISINK
Current that may be sunk by this pin at low state
0.5 mA
VSENSE+, VSENSE-
VSENSE+ and VSENSE- lines are the remote sense lines for regulation. Each line will compensate for a maximum of 200 mV.
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.
This is an open collector/drain output. This pin is pulled high by a 1.0 kohm resistor connected to 3.3 V inside the power supply. It is recommended that this pin be
connected to a 100 pF decoupling capacitor and pulled down by a 100 kohm resistor.

ISINK
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. More details in the Timing Section.
This is an open collector/drain output. This pin is pulled high by a 1.0 kohm resistor connected to 3.3 V inside the power supply. It is recommended that this pin be
connected to a 100 pF decoupling capacitor and pulled down by a 10 kohm resistor.
