1. Parts ending with EiC have optional TRIM and SS pins fitted.

2. Current is quoted when output is 95% of regulated voltage.

3. Calculated using MIL-HDBK-217F with nominal input voltage at full load.

4. For applications requiring UL 1950 recognition, input voltage must not exceed 60VDC.

5. A minimum load of 10% of rating is recommended for typical applications.

6. Absolute maximum value for 30 seconds. Prolonged application may damage the product.

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 heat-

sinking. 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.
