EN6337QA 3A PowerSoC - 22nF Capacitor

Question

Dear all,

i have a question with regard to the EN6337QA DC-DC Step-Down Converter.

- According to Page 2 of the datasheet there can be a 22nF capacitor placed between PG and BGND.

- According to Page 18 of the datasheet this 22nF capacitor is placed between PG and BTMP.

Can anyone explain the difference of these two options?? Thank you very much.

Hi,

I assume that PG-22nF-BTMP is correct. The altera website (https://www.altera.com/products/power/devices/powersoc-dc-dc-step-down-converters/en6337qa.html) says that it's pin-compatible with the EN6347QA, and in the datasheet of the en6347qa (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/ds/en6347qa_10318.pdf) it says to connect PG-22nF-BTMP both in the pin table and in the example schematic.

You should contact Altera anyway, and if it's jus to let them know about the ambiguity.
