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 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.

1. Parts ending with EiC have optional TRIM and SS pins fitted.
2. Calculated using MIL-HDBK-217F with nominal input voltage at full load.
3. 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.
