*With package soldered to 0.5 square inch copper area over backside ground plane or internal
power plane, θJA can vary from 30 °C/W to more than 40 °C/W. Other mounting techniques
can provide a thermal resistance lower than 30 °C/W.

Pin Function Descrition
Remote Voltage Sense. Connect this pin to the load to permit true
remote sensing and avoid trace drops.
Adjust or Ground. On the FAN1582, this pin forms the feedback to
determine the output voltage. On the FAN1582-1.5 and -2.5, connect this
pin to ground.
Output Voltage. This pin and the tab are output.
Control Voltage. This pin draws small-signal power to control the
FAN1582 circuitry. Connect to a voltage higher than VIN, as shown in the
applications circuits.
Input Voltage.
