When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external
capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the
additional external capacitance for reliable start up.

DESCRIPTION
The NMD series of DC/DC converters are ideally
suited to applications where a potential difference
exists between loads, e.g. motor control circuits.
The twin outputs offer cost and space savings
by consolidating two DC/DC converters into one
package. All of the rated power may be drawn
from a single output provided the total load does
not exceed 1 watt.

1. Calculated using MIL-HDBK-217F with nominal input voltage at full load.
2. See derating curve.
3. Supply voltage must be disconnected at the end of the short circuit duration.
All specications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specied.
