Hi,
i have 2 questions:
1- i was planning to use INA current sensor for 400V output but in Low-Side configuration due to common mode voltage issue. TIDA-00528 uses a more complex…
Part Number: PMP21697 Why does the Buck Synchronous Rectifier switch ( Q3 ) not have a parallel FET but all the other switches are parallelized? Also, what's the purpose of the R19 & C19 and R20 & C20 strings?
Other Parts Discussed in Thread: MOTOR-DRIVE-FET-LOSS-CALC , SYNC-BUCK-FET-LOSS-CALC We are using Office 365 (macros are activated) and when I klick on Start FET selection and then on 3c "Click Here FET1" nothing happens. Only the sheet is flashing and…
Part Number: CSD95379Q3M Hi Team,
We've been trying to use the SYNC-BUCK-FET-LOSS-CALC to calculate the losses of CSD95379Q3M.
It seems like every time I press any of the '--> --> CLICK HERE <-- <--' buttons a new selection windows starts to open but…
