The Learning Circuit 42 - Replacing MLCCs with Polymer Capacitors

Polymer capacitors offer low ESR and high capacitance in a small package. See what happens when a tantalum polymer replaces an MLCC in a DC-to-DC converter. Or, check the result of replacing a traditional electrolytic capacitor with an aluminum polymer. For fun, James shows measurements on a modern switching power supply and goes back to a classic 8-bit favorite, the Commodore 64.
