AMC1351: About the detailed design part and calculations

Emre Rasim

Part Number: AMC1351

Hello, I was redoing the calculations in the detailed design section to use in my own project. I find the RSNS-EFF value, which is 9.96 kOhm in the photo, to be approximately 50.352 kOhm. I want to ask, am I making a mistake or is there an error in the data sheet?ti /resized-image/__size/320x240/__key/communityserver-discussions-components-files/14/T_3101_forumquestion1.png

Hi Emre,

Thank you for bringing this to our attention. I do think you found an error in the data sheet. The RSNS_EFF = 9.96 and the 49.9 kΩ in the table appear to be incorrect. Using 52.3 kΩ as RSNS and 1.25 MΩ as R_IN, I got 50.2 kΩ as RSNS_EFF. Additionally, you can use this excel calculator to try different values. We will work on correcting this data sheet.

Best regards,

Eva
