- In a buck converter, is there any correlation between switching transition time and decoupling capacitor requirement? As per the TI document attached input decap values are only determined by input ripple current and switching frequency.
- In the text book "A to Z Switching power supplies_Sanjay Maniktla", it was mentioned the noise has little to do with the basic switching frequency of the converter itself — it is the transition that is responsible for most of the noise, and all its attendant problems. Is the author referring to voltage spikes (noise) due to stray inductance alone?
Thanks in advance
