  • PMP10783: Measured Inductor current waveform is not proper

    Part Number: PMP10783 Hi, I have tested this design ( Rectifier section is not implemented ) and we found following observations. These are the waveforms for input voltage of 150VDC & 250VDC. ( Rectifier section is not implemented ). Blue color…

  • RE: PMP10783: PMP10783 stability Query; TI power stage designers tool shows phase margin is not meeting the criteria.

    New device intentionally to have higher VDD UVLO levels so that SiC driving voltage is higher, which is optimized for SiC.

  • PMP10783: Does this design works for low input voltage?

    TI Thinks Resolved
    Part Number: PMP10783 Other Parts Discussed in Thread: PMP20708 Hello, I want to know if I use the same design for low input voltage ( say 30Volts ).? Since during low input voltage for getting the same output voltage I assume duty cycle of the converter…
