I have a development project to monitor some information in an industrial environment in which sensors are built into the board. But I will need to add a modification that allows non-invasive readings of sensors already installed in companies that fo...

I found this part of the datasheet for the STBB3JCC component a little confusing. Could someone help me calculate the ideal resistor values to have an output of 3.3V? My board is powered by a lithium battery that varies from 3V to 2V. The output r...

Hello, I'm new here. I'm doing a project with STBB3J components and I believe I didn't correctly understand how to calculate the resistors that control the output voltage. I followed the example of the same application circuit, which is this (page 4 ...

Ok, and using a sensor with Rsense, which would be the most suitable for this application, considering the smallest Rsense possible?

I found the problem.The component I bought is the STBB3JCC, which has a feedback voltage of 0.1V and I was looking at the STBB3JC datasheet, which has a feedback voltage of 0.5V.I will produce a new board with the resistors already corrected, and wit...

Ok. I was wondering if it would be possible to connect the MODE/SYNC pin directly to GND or if I would need a resistor.As for the inductor, I'm using this model "MWSA0402S-100MT Sunlord | C408339 - LCSC Electronics", the typical saturation current is...
