  • TIDA-00528: Power Loss of P-FET

    Part Number: TIDA-00528 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 method and measures on the high-side. now i am…

  • PMP21697: Boost and Buck Leg FET Count

    Resolved
    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?

  • RE: TIDA-00443: Boost diode loss calculation

    Hi, Milarepa actually, 0.5*f*C*U^2=0.5*fsw*Vout*Qrr Regards Hely

  • RE: DRV8300: Possible to use DRV8300 as non-boosted gate drive outputs (half for P FETs, swapping high side and low side inputs/outputs)?

    Hi Amaresh, Thank you for your patience. While it would be possible to forgo the bootstrap capacitor if you are using a P-FET on the high side of the gate driver, it is not recommended as the device was designed with the intention of being used with 2…
