Hi,
My customer is considering using LM5155.
Many capacitors are used as output capacitors on the LM5155EVM-BST.
Could you tell me how these capacitors were designed for their reference?
Best Regards,
Kuramochi

Hi Kuramochi-san,
Sorry if the app note is not clear enough to the readers. The output capacitor is chosen by ripple voltage spec, ripple current handling capability, and energy storage. In practical design, power supply designers usually choose a combination of electrolytic and ceramic capacitors for optimal cost/performance ratio.
Hope this helps.
Thanks,
