Hi,
In the Layout example of TPS53355 datasheet, a smaller package capacitor is shown along with 22uF bulk capacitors at the input section ( VIN pins).
But the example schematics has only bulk capacitors at the input and even webench suggests to put only bulk capacitors.
So please let me know is there any requirement to keep a smaller value capacitor ( such as 1uF or 4.7 uF) along with bulk at the input section.
Thanks & Regards,
Madhu
