Are logic level gate mosfet slower than regular mosfet?

Thanks: and I have been struggling to keep files below 100kB |O

Thanks for advice Ian

Back on piste!

The LT1157 may be of interest. It is a gate driver with an-onboard charge pump to generate a gate drive voltage suitable for standard MOSFETs.

As far as I can tell, the charge pump runs all the time, and is not dependent on input signal transitions, so the LT1157 is suitable for "DC" switching.

Ian.M:
Interesting chip, but its strictly for low speed switching.   Even 1KHz PWM would be too fast for it.
