Function
Shutdown. Pulling this pin low
will disable the output.
Device Ground. This pin should
be tied to system ground closest
to the load.
Output Voltage Sense. This pin
is connected to the MOSFET’s
drain and directly to the load for
optimal load regulation. Bypass
to ground with a 10 F or larger
capacitor.
Gate drive for the external
MOSFET.
Input Voltage. This is also the
positive terminal connection of
the current sense resistor.
Current Sense. Used to sense the
input current by monitoring the
voltage across the current sense
resistor. It is connected to the
more negative terminal of the
resistor as well as the power
MOSFET’s source pin. IS pin
should be tied to the V
the current limit feature is not
used.
No Connect.
