FEATURES
DESCRIPTION
The NPH25S 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
heatsinking, 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
recognised by Underwriters Laboratory (UL)
to UL 1950 for operational insulation, file
number E179522 applies.
