These power converters do not have internal input filters and do require external input
These power converters require a minimum 10% loading to maintain specified regulation.
Operation under no-load conditions will not damage these devices, however, they may
not meet all listed specifications.
and output capacitors to achieve rated specifications. Application-specific internal input/
output filtering can be added upon request. Contact DATEL for details.
On/Off Control pins are included on "D5" models only. See Technical Notes for details.
Applying a voltage to the Control pin when no input power is applied to the converter can
cause permanent damage to the converter.
Cases can be provided with 6-sided shielding. Contact DATEL for details.

Absolute Maximum Ratings
These are stress ratings. Exposure of devices to any of these conditions
may adversely affect long-term reliability. Proper operation under conditions
other than those listed in the Performance/Functional Specifications Table is
not implied. Storage temperatures have been verified for 168 hours.
