Ceramic Input Capacitors Can Cause Overvoltage Transients
Goran Perica

A recent trend in the design of portable devices has been Building the Test Circuit
to use ceramic capacitors to filter DC/DC converter inputs.
To illustrate the problem, a typical 24V wall adapter used
Ceramic capacitors are often chosen because of their
