FILTER CIRCUITS

Value

EXTERNAL CAPACITANCE

LOUT

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.
