models or from each output to common for dual
output models. For noise sensitive applications,
the use of 3.3 µF capacitors will reduce the
output ripple.
3. Transient recovery is measured to within a 1% error
band for a load step change of 75% to 100%.

ac-impedance source. An input source with a
highly inductive impedance may affect the sta-
bility of the converter. In applications where the
converter output loading is high and input power
is supplied over long lines, it may be necessary
to use a capacitor on the input to insure start-up.
In this case, it is recommended that a low ESR
(<1.0 at 100 kHz) capacitor be mounted close
to the converter. For 24V input units a 4.7 µF is
recommended and for 48V input models, a 2.2 µF.
8. It is recommended that a fuse be used on the
input of a power supply for protection. See the
table above for the correct rating.
5. The recommended reflow settings are a peak
temperature of 245 °C for a maximum period
(TPK) of 10S and a time above liquidous (TL) of <60
