UCC3895: SR control of UCC3895

Part Number: UCC3895
Other Parts Discussed in Thread: UCC28951

Hi team,

UCC3895 is a non support SR control solution, so many user choose OUTA and OUTB signal for SR control.

But still has some project choose OUTB and OUTD for SR control.

What is the different of these two SR control operations?

And which one is better?


  • Hi, Roy

    below is the right timing of primary Gate signal and SR gate signal, OUTE/F is SR gate signal. the overlap of OUTA and OUTD is D, SR gate signal should be 1-D. so whatever OUTA/B or OUTB/D for SR control is the the best solution, the best solution is UCC28951 which has SR integration.
