Function Description
This section explains how to implement the functions found on the AIF - PFC Series. All signals are on primary side.
PFC Enable Input (PF ENABLE)
The enable pin is a TTL compatible input used to turn the output of the module on or off.
For module with no suffix, the output is enabled when the PF ENABLE (pin 16) is open or driven to a logic high > 2.2V.
The output is disabled when the PF ENABLE is connected to S GND (pin 13) or driven to a logic low of < 0.8V (but not
negative).
For module with suffix “N”, the output is enabled when the PF ENABLE is connected to S GND or driven to a logic low <
0.8V (but not negative). The output is disabled when the PF ENABLE is open or driven to a logic high > 2.2V.
S GND (Signal Ground)
The S GND pin is connected to the internal common ground of the module. It is also internally connected to the –O/P
terminals.
NOTE:
When connecting S GND to external circuitry care must be taken to ensure that the current flowing through this pin is kept
below 25mA.
