Note A:
Characteristic data has been developed from actual products tested at 25°C. This data is considered typical data for the ISR.
Note B:
SOA curves represent operating conditions at which internal components are at or below manufacturer’s maximum rated operating temperatures.

Pin Descriptions
+Vin:
The positive supply voltage input for the module
with respect to the common GND.
+Vo:
This is the regulated output voltage from the mod-
ule with respect to the common GND.
GND:
The common GND node to which the input, out-
put, and external control signals are referenced.
Sense(–):
Provides the regulator with the ability to sense
the set-point voltage directly across the load. For opti-
mum output voltage accuracy this pin should always be
connected to GND, even for applications that demand a
relatively light load.
Sense(+):
When used with Sense(–), the regulation cir-
cuitry will compensate for voltage drop between the
converter and the load. The pin may be left open circuit,
but connecting it to +Vo will optimize load regulation..
Inhibit:
This is an active low input, which is referenced
to GND. Driving this pin to GND disables the module’s
output voltage. If Inhibit is left open-circuit, the output
will be active whenever a valid input source is applied.
Vo Adjust:
This pin is used to trim the output voltage to a
value within a range of up to ±10% of the setpoint. The
adjustment requires an external resistor. The resistor is
connected from Vo Adjust, to either the Sense(–) or Sense(+),
in order to adjust the output voltage either up or down,
respectively.
Margin Up:
When this pin is connected to Sense(–), the
output voltage is increased by 5% of the nominal setpoint.
The Margin Up and Margin Down control inputs provide
a convenient method for testing the operation of the
load circuit over a ±5% variation in the supply voltage.
Margin Down:
When this pin is connected to Sense(–), the
output voltage is decreased by approximately 5% from
the nominal.
