EN6337QA 3A PowerSoC - 22nF Capacitor

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. 

 

Link to datasheet: https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/ds/en6337qa_10395.pdf 

 

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. 

 

 

Best regards,
