Notes:
1. Load regulation is measured for an output change of 20%
to 100%.
2. When measuring output ripple, it is recommended that an
external 0.33 μF ceramic capacitor be placed from the +Vout
pin to the -Vout pin. For noise sensitive applications, the use
of 0.47 μF capacitors will reduce the output ripple.
3. Operation at no-load will not damage these units. However,
they may not meet all specifications.
4. The converter should be connected to a low ac-impedance
source. An input source with a highly inductive impedance
may affect the stability 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 (ESR <1.0Ω at
100 kHz) capacitor be mounted close to the converter. For
5V input units a 2.2 μF is recommended, for 12V input units,
a 1.0 μF, and for 24V input units, a 0.47 μF.
5. 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.
