2. Specifications for Inductor

We recommend an inductor with these specifications: an inductance of 1mH, rated current of at least 500mA,

and good performance with DC superimposition. Please note there must be no magnetic saturation in the

inductor.

The following waveforms show the output ripple voltage on VO-1 for good versus bad inductors. These

waveforms are produced with output VO-2 unloaded and the scope coupling set to AC.
