6 FAQs about [Capacitor model selection criteria]
What are the selection considerations of output capacitors?
This application note describes the selection considerations of output capacitors, based on load transient and output impedance of processors power rails. Presently, there are no specific tools available for non-Intel processor output capacitors selection in multiphase designs.
How to choose a capacitor?
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.
Does output capacitor selection meet non-Intel processor requirements?
Analytical and experimental results show that output capacitors selection is optimized for load transient and output impedance, to fulfill non-Intel processor requirements. D-CAP+ is a trademark of Texas Instruments. High-performance microprocessors require low voltage and high current voltage regulator modules(VRM).
What factors affect capacitor selection?
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.
What should a capacitor's voltage rating be?
Apart from nominal capacitance, the voltage rating is the second most important parameter that must be essentially factored in. The capacitor’s voltage rating should always be at least 1.5 times or twice the maximum voltage it may encounter in the circuit. Capacitors are not as reliable as resistors.
Can a capacitor be installed in series?
Though there are few cases to install a capacitor in series. In my designs, I am not allowing to a voltage stress of more than 75%. This means, if the actual circuit voltage is 10V, the minimum capacitor voltage I will select is 13.33V (10V/0.75). However, there is no such voltage. So, I will go to the next higher level that is 16V.
