LTspice: Splitting a gate drive into two separate gate drive pulse streams?


Well-Known Member
Thanks Ronsimpson, the LTC3721 has slope compensation and a rather low current sense voltage reference, and takes longer to simulate.
The LT1243 is very simple and straightforward.
(I like the LTC3721 though and if i was doing it on the bench i would consider using it in some cases.)

The attached (LTspice and schem) shows how it can be done with the LT1243 …but I am getting an unfortunate little spike in the waveform streams as shown.

Any better ways?

Your little spike may be a sim artefact. Putting even 1pF in parallel with S1 or S2 increases the spike dramatically.
