EXTERNAL CAPACITANCE
Although these converters will work without
external capacitors, they are necessary in
order to guarantee the full parametric
performance over the full line and load
range. All parts have been tested and
characterised using the following values and
test circuit.
OUTPUT LOAD
The minimum rated load across the whole
input voltage range is 25% of the full load
output. It is important to take care that the
load does not fall below this as the output
ripple will greatly increase. While this
condition will not harm the device the
resultant increase in output ripple could cause
customers’ application to malfunction.
