near sea level altitude, natural convection airfl ow. All models are tested and specifi ed
with external parallel 1 μF and 10 μF multi-layer ceramic output capacitors. The ex-
ternal input capacitor is 4.7 μF ceramic. 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.
Input fi ltering is Cbus=220 μF, Cin=33 μF and Lbus=12 μH.
