DESCRIPTION
The NPH15S series of DC/DC converters combines
ease of application with versatility. The pin pattern
is based on the popular industry standard, but two
additional pins may optionally be fitted to provide
a variety of features not commonly found on units
of this type. High efficiency enables full rating to
be achieved in a small package without heat-
sinking, and a high surge capability will provide
for start-up and transient loads, whilst being
thermally protected against sustained overload.
Overload protection of the “constant current” type
ensures start-up into complex load conditions. The
copper case achieves efficient heat transfer and
screening. The product range has been recog-
nised by Underwriters Laboratory (UL) to UL 1950
for operational insulation, file number E151252
applies.
