All specifications typical at Ta = 25°C, nominal input voltage and full load
unless otherwise specified.
The information and specifications contained in this data sheet are believed
to be correct at time of publication. However, we accept no responsibility
for consequences arising from printing errors or inaccuracies.
Subject to change without notice.
NOTE
1) Typical value at nominal input voltage and full load.
2) Tested by nominal Vin and constant resistor load.
3) Measured input reflected ripple current with a simulated
source inductance of 12uH.
4) Exceeding the absolute ratings of the unit could cause
damage. It is not allowed for continuous operating.
