Part Number: TPS562201
While reviewing the reference design for TPS562201 in WebBENCH I noticed that three GRM188R60J226MEA0 ceramic 22uF 6.3v caps were used in parallel to achieve ~24uF after derating, and a much lower total BOM cost compared to a single 35v or 50v 22uF cap. Creative!
Does this approach to reduce the total BOM cost have a negative impact on the life of the capacitors? In elevated temperatures of ~50C?
