The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors. Ceramic capacitors placed right at the input of the regulator reduce ripple voltage amplitude.
The approach of the seminar is to provide you the wright criteria to support you with capacitor selection for your particular design. The criteria and effects. which are import to keep in mind for the proper selection. are the basic topics of this seminar as well as selection criteria and advices for the following capacitor technologies:
The transient requirements of your system are very important. The load transient amplitude, voltage deviation requirements, and capacitor impedance each affects capacitor selection. Other important issues to consider are minimizing PCB area and capacitor cost.
A capacitor with an appropriate ripple current and working voltage rating should be chosen. Polarity and Reverse Voltage – If an electrolyte capacitor is used in the circuit, it must be connected in the correct direction. Its reverse voltage rating should be at least twice the possible reverse voltage in that branch of the circuit.
The most important parameters are the magnitude of the load transient (ΔI) and the distributed bus impedance to the load. The selection of the output capacitors is determined by the allowable peak voltage deviation (ΔV). This limit should reflect the actual requirements, and should not be specified lower than needed.
The selection of the output capacitors is determined by the allowable peak voltage deviation (ΔV). This limit should reflect the actual requirements, and should not be specified lower than needed. The distribution bus impedance seen by the load is the parameter that determines the peak voltage deviation during a fast transient.
