Other Parts Discussed in Thread: TIDM-DC-DC-BUCK, , TLV2621, OPA365
I am designing a DCDC 40V-100V converter with digital control very similar to TIDM-DC-DC-BUCK(https://www.ti.com/tool/TIDM-DC-DC-BUCK). I need some help choose/design the inductor current sensing circuit, since my system has a much higher output voltage, it needs withstanding over 100V common mode voltage. Does this differential mode opamp topology still work? what should the parameters be? is OPA353 the best choice, etc.
Thanks a lot!
