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. Recommended pull-up resistor
to 12 VSB is 8.2 k with a 3.0 k pull-down to ground. A 100 pF decoupling capacitor is also recommended.

PSKILL_L
First break/last mate active LOW signal which enables/disables the main output. This signal will have to be pulled to ground at the system side
with a 220 ohm resistor. A 100 pF decoupling capacitor is also recommended.

Output Signals
INPUT_OK
Signal used to indicate the presence of DC input to the power supply. A logic level HIGH will indicate that the DC input to the power supply is
within the operating range while a logic level LOW will indicate that DC input 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 recom-
mended that this pin be connected to a 100 pF decoupling capacitor and pulled down by a 100 kohm resistor.

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 DC input or system shutdown request. More details in
the Timing Section.
