pdntool_header1.pngStart PDN Tool…Use the PDN Tool to optimize how many bypass caps you actually need and make sure you have enough of the right types to cover the frequencies of interest.

Three Simple Steps

1. Define the capacitor types C1..C5 with C, ESR and ESL

2. Define the impedance target in mΩ to a max frequency

3. Hit Optimize and see how many capacitors you need of each type

Power Integrity

This is key to solid digital designs and helps a great deal in passing EMI tests as well.

The tool may look very simple, but this technique has proved sufficient in thousands of designs over the last many years.You can buy much more sophisticated and advanced tools, but if you are only designing circuits at the board level, the real value is questionable compared to this fast and easy tool.

May the power integrity be with you…
