DESCRIPTION
The NPH15S series of DC-DC converters com-
bines 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
heatsinking, and a high surge capability will pro-
vide 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.
