NDS Series Data Sheet
10 W SMT DC-DC Converters, 1.5 – 5 V Output
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings may cause performance degradation, adversely affect long-
term reliability and cause permanent damage to the converter. Specifications apply over specified input voltage,
output load and temperature range, unless otherwise noted.
