DESCRIPTION
The NPH10S 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. Thermally protected against
sustained overload. 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.

1 If optional pins ADJ and SS are required (as indicated in the pin connections diagram) prefix the ending “i” with
an E when ordering, e.g. NPH10S4803Ei.
2 Current is quoted when output is 95% of regulated voltage.
3 For applications requiring UL1950 recognition, input voltage must not exceed 60VDC.
4 A minimum load of 10% of rating is recommended for typical applications ; see application notes.
5 Optional - Where fitted.
6 Absolute maximum value for 30 seconds. Prolonged operation may damage the product.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
