3.1
Input/Output Connectors and Jumper Description
NOTE:
Connectors J1-J3 and J12-J14 are blank SMB connectors. These can be populated, or wires
can be soldered directly to them. The middle connection of the connector is the signal, while
the four edge connections are all ground.
3.1.1
J5 - Input
Input for power. Connect supply to this connector.
3.1.2
J6- Feedback
Determines the output voltage. Connected to V
TAP
through R

with standard setup.
3.1.3
J7 - ERROR
Error output connector. This active low output determines if the output voltage is within 6% of its expected
value.
3.1.4
J4/J8 - GND
Return path connectors.
3.1.5
J9 - Output
Regulated output voltage connectors.
3.1.6
J10 - Sense
Output voltage sensing connectors.
3.1.7
J11 - Shutdown
Device shutdown connectors. By shorting the middle pin of J11 to the pin labeled as N, the device
remains active. If the middle pin of J11 is shorted to the pin labeled Y, the device will shutdown. See
Table 2
for shutdown jumper position connection.
