Energy Storage Using Supercapacitors: How Big is Big Enough?
In a power backup or holdup system, the energy storage medium can make up a significant percentage of the total bill of materials (BOM) cost, and often occupies the most volume. The key to optimizing a solution is a careful selection of components so that holdup times are met, but the system is not overdesigned.
Low ESR capacitor: what does it mean/how to select one?
I''m trying to design a PCB including a TPS5450 step down converter. For the boost capacitor, the datasheet asks for a "low ESR ceramic capacitor": 7.3.5 Boost Capacitor (BOOT) Connect a 0.01-μF, low-ESR ceramic …
Is there any downside to using a larger than needed smoothing capacitor?
I work with low-power DC voltage regulators. I am already aware of the formula to calculate the size of smoothing capacitor(s). This can be an iterative process of testing one size with a scope and $begingroup$ This reason may be buried in one of the many good answers Some (only) regulators can be damaged by the output capacitor …
