Pin Assignment

Pin #
Remote Sense
The remote sense regulates the output voltage across the sensing connections, and should be connected at the point on the board where
regulation is desired. It is used to compensate for contact and distribution losses to the load. Efforts should be made to minimize these
losses to help reduce noise and improve efficiency of the system.
The voltage between remote sense pins and the output terminals must not exceed the output voltage sense range as specified in Table 2.
