Engineers note: Capacitors are key to voltage regulator design
The single most commonly made mistake in component selection for capacitors in switching regulators may be in the ripple current specification. Ripple current is the RMS value of the current flowing into and out of the capacitor each time the switch turns ON and OFF. Referring to Figure 1, there is a ripple current flowing in both CIN and
Switched-capacitor converter | How it works, Application
Capacitor Selection: The capacitors need to have a high charge storage capacity and a low equivalent series resistance (ESR) to efficiently handle power conversions. Switching Frequency: A higher switching frequency allows for the use of smaller capacitors, further reducing the size of the converter. However, this can also …
