Notes
➀
Unless otherwise noted, all specifications apply at Vin = nominal, nominal output voltage and full
output load. General conditions are near sea level altitude, no base plate installed and natural con-
vection airflow unless otherwise specified. All models are tested and specified with external paral-
lel 1 μF and 10 μF output capacitors and a 22μf external input capacitor (see Technical Notes). All
capacitors are low-ESR types wired close to the converter. These capacitors are necessary for our
test equipment and may not be needed in the user’s application.
➁
Input (back) ripple current is tested and specified over 5 Hz to 20 MHz bandwidth. Input filtering is
