  • TPS543B20: Question about external sync loss in standalone mode

    Resolved
    Part Number: TPS543B20 Hi Experts, I have a quick question about the loss of sync in standalone mode. If the customer uses the external clock at the initial and then the external clock disappears, does the device shut down permanently? Or operates as…

  • PMP21697: Boost and Buck Leg FET Count

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

    Hi Alicia, Here is a schematic snippet showing how we are planning on using the DRV8300: To get over the boost undervoltage lockout, we are grounding all the source feedback pins, and also bypassing the internal boost diode as it is not necessary with…
