III. OTHER XDCP POWER SUPPLY
APPLICATIONS
A digitally controlled potentiometer can be used in any
application requiring electronic control of a potentiom-
eter setting to adjust circuit parameters. Some suggested
examples are:
1. Automatic calibration during production test is possible.
A “bed-of nails” interface, similar to that used for para-
metric testing, provides a low cost access to the XDCP
programming pins. Automating the calibration process
reduces labor cost and improves product uniformity.
2. The power supply customer can be given control over
certain parameters. For example, output voltage adjust-
ment for margin testing can be easily programmed by the
customer and offer far more options for adjustment than
the conventional approach.
3. If optimizing dynamic response is a requirement, the
XDCP programmability can be used to compensate for
the wide initial tolerance of the feedback optocoupler
current transfer ratio. Typically this tolerance is plus or
minus 50% which forces the designer to reduce band-
width by an octave to accommodate this tolerance.
4. For laboratory type power supplies, the XDCP device can
replace front panel mechanical potentiometers. Not only
does this offer the advantages of cost and reliability, but
allows computer control of the front panel adjustments.
Power supplies used in automatic test equipment can
avoid the cost of A/D converters.
Xicor XDCP devices offer a reliable alternative to the
mechanical potentiometer, plus it offers the advantage of
electronically controlled adjustment.
