When a non-regulated source is used as a front end, make sure
that the voltage fluctuation together with the ripple voltage will not
exceed the input voltage range.

Select the converter that is able to handle the start-up current (Ip).

When too much stress is applied on the input/output pins of the
unit, the internal connection may be weakened. As below Fig. 9.1,
avoid applying stress of more than 19.6N (2kgf) on the pins hori-
zontally and more than 39.2N (4kgf) vertically.
The input/output pins are soldered on PCB internally, therefore,
do not pull or bend them with abnormal forces.
When additional stress is expected to be put on the input/output
pins because of vibration or impacts, fix the unit on PCB (using sil-
icone rubber or fixing fittings) to reduce the stress onto the in-
put/output pins.
