For decades, power-supply designers have set their inductor ripple current to somewhere between 20% and 40% of their power supply’s full rated output current. This is considered a good starting point ...

A battery alone may not be capable of supplying complex systems with all the voltage rails necessary to function properly. Applications such as automotive LED drivers, audio amplifiers, and ...

Microprocessors and application-specific integrated circuits (ASICs) require low-voltage, high-current power supplies. These supplies usually have very strict requirements on output-voltage deviations ...
