I have quetions of UCC2808A-1.

1. stability

I think UCC2808A-1 is the voltage control by the width of ON time. Is this correct?

If it is correct, I think it is difficult to keep the stability of the wave shape, when the load is light and the dead time is long .

Could you please advise the solution of the condition?

2. Snubber circuit

There is the snubber circuit in the datesheet page 6.

Could you please how to set constants of components?

Best regards,

Atsushi
