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
‘Vin’ and ‘Vout’ power connections. It is also the 0 VDC
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
low-level ground signal to this input disables the module’s
output and places the regulator in “standby” mode. When
in standby, the input current drawn by the regulator is
significantly reduced. If the STBY input is left open-
circuit, the module will produce an output whenever a
valid input source is applied.
VID0–VID4:
Selects the set-point output voltage of the
regulator according to the applicable program code (See
programming information). Each input, VID0 through
VID4, is either 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 VID4.
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 VID4. 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.
