Description
Main output voltage
Main output voltage, return
VOUT remote sense, positive node input, connected to the
+ve load point
VOUT remote sense, negative node input, connected to the
-ve load point
Standby voltage output
Standby voltage, return, tied internally to Output Return
Active load sharing bus
Input AC Voltage “OK” signal output (Internal pull up is
10kΩ to Vsb)
Power good signal output (Internal pull up is 10kΩ to Vsb)
Floating pin will turn off P/S (shorter pin, last-make and
first-break contact for hot plugging). This signal overrides
PS-On in disabling the Main Output
Internally tied to Vsb return
Internal 1K ohm pull-up to Vsb, (accepts open collector/
drain drive), This signal to be pulled low to turn-on power
supply
I2C serial data bus
I2C serial clock bus
Address input 0, internal pull-up to Vsb
Address input 1, internal pull-up to Vsb
Address input 2, internal pull-up to Vsb
