Hi,
I want to build a switching circuit that is as fast as possible (off->on in ~1ns would be nice, must be less than 40ns). Maximum loads will be 0.5A and 60V. I have no idea what the requirements are to build a circuit for this speed, so hopefully the people here can help out, first of all with part selection. I believe N-channel is faster than P, which means I put the switch between the load and ground?
I just found out today that fast MOSFETs need a separate driver (to provide charge in a burst to the gate capacitance). Actually I will have a low frequency (i.e. repetition rate), and high switching speed, but I think I still need the driver? Are there any options where they are integrated?
My first attempt would be:
switch: http://www.st.com/stonline/products/literature/ds/6772/stn1n20.pdf
driver: http://www.nxp.com/acrobat_download/datasheets/PMD2001D_1.pdf
Hope someone can give me some tips
