Pin Descriptions
Vin:
The positive input voltage power node to the mod-
ule, which is referenced to common GND.
GND:
This is the common ground connection for the
‘V
in
’ and ‘V
out
’ power connections. It is also the 0VDC
reference for the ‘STBY’ control input.
STBY:
The STBY pin is an open-collector/drain nega-
tive logic input that is referenced to GND. Applying a
ground signal to this input will disable the module’s
output and place the regulator in “standby” mode.
When in standby, the input current drawn by the regula-
tor is significantly reduced. If the STBY input is left
open circuit, the module will produce an output when-
ever a valid input source is applied.
VID0–VID3:
Selects the set-point output voltage of the
regulator according to the applicable program code (See
programming information). Each input, VID0 through
VID3, must either be connected to ‘Sense(–)’ or left open
circuit.
Vout:
The regulated positive power output with respect
to the GND node. The set point voltage at this node is
defined by the status of the pins VID0 through VID3.
Sense(+):
Provides the regulator with the capability to
regulate the set-point voltage at the load. When used
with ‘Sense(–)’, the regulation circuitry will compensate
for voltage drop between the converter and the load.
This pin may be left open circuit, but connecting it to
‘Vout’ will improve load regulation.
Sense(–):
This is the logic ‘0’ reference for the inputs
VID0 through VID3. It also provides the regulator with a
differential remote sense capability when used with the
‘Sense(+)’ input. For optimum output voltage accuracy
this pin should always be connected to GND.
MARGDN:
This is an open-collector/drain negative logic
input. Applying a ground signal to this input increases
the output voltage of the module by up to 5%. The con-
trol provides a convenient method for testing the operation
of the load circuit over its supply voltage tolerance mar-
gins.
MARGUP:
An open-collector/drain negative logic input
that operates similar to the
MARGDN
control. Applying
a ground signal to this input automatically decreases the
output by up to 5%.
