Hello team,
my customer is planning to use the ISOW7821 in their new design but are struggling to find a good step down converter that could provide the 5V to the ISOW7821.
Do you have any recommendation? Maybe you have already seen some of the most popular buck used in combo with this device. As a first choice we are thinking of using the TPS560200 but if you have any suggestion, please let me know. If not, I'll try to ask on the power management forum starting from the specs required by the ISOW.
Also, the ISOW7821 is protected against short-circuit at the output but the maximum DC current is not shown: for 5V -> 5V application I find in the DS an indication of a typical DC current of 137mA (but not exactly the maximum).
I ask you if there is a maximum current data or if it is more appropriate for me to have a limitation on the primary (Vcc side of ISOW7821); in case I thought of using a TL331 comparator with input shunt, hysteresis and output driving the Enable of the TPS560200.
Please let me know what you think or if you have any suggestions.
Thank you and best regards,
Adrian
Hi Adrian,
Once the requirements are clear, checking with the power management forum can also help you get additional feedback.

Hi Adrian,
Any follow-up thoughts on the above? Or did you decide to go with the TPS560200...?

Hi Abhi,
sorry but I'm still waiting for a feedback from the customer. I'll update you in case anything changes for sure.
Thanks again for checking in!
