Contact UsSLTA055–FEBRUARY 2006 Input and Output Capacitor Selection
Bulk capacitors control the voltage deviation at the input when the converter is responding to an output load transient. The higher the capacitance, the lower the deviation. Therefore, the size of the input bulk capacitor is determined by the size of the output current transient and the allowable input voltage deviation.

The relevance of ESR to capacitor selection is twofold: 1) it influences the AC response of the capacitor, and 2) it imposes limits on the amount of AC current that can be permitted to flow through the capacitor due to thermal limitations. Current flow through a capacitor''s ESR results in I2 R losses just like any other resistor, causing a temperature …

What is a Capacitor and What does it do. A capacitor is an essential electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by a non-conductive material called a dielectric. When a voltage is applied across the plates, electric charge accumulates on them, creating an electric field between the plates.
