Other Parts Discussed in Thread: LM5117
Hello team,
When the customer used Webench simulation, The result of Cout was 150uF which is hybrid electrolytic capacitor with maximum
12mΩ ESR and 2 x 47uF ceramic capasitors. However hybrid electrolytic capacitor is expensive, then he has some questions.
1. Can we replace ceramic capasitors such as 47uF x 3pcs from 150uF hybrid electrolytic capacitor?
2. If yes, Should we remove ceramic capacitors which is placed in parallel(47uF x 2) or shoud we use 5 x 47uF ceramic capasitors?
3. Does the replacement causes phase/gain margin If we can use 3x or 5x ceramic capacitors?
Your comment would be so appreciated.
Best Regards,
Akihisa Tamazaki
