When the L value of an inductor is changed from the recommended value, in some cases the efficiency may be improved, but are there any trade-offs?
- There are cases in which, by setting an inductance value to be higher than the recommended value, the efficiency under light loading can be improved. As trade-offs, the frequency characteristics and ripple current magnitude change, and so the device operation and behavior must be studied and verified thoroughly.
