To reduce EMI you may want to have asymmetric turn on/off paths so that you can turn the MOSFETs on a little bit slower than you turn them off. I have also used high pulse-current PNP transistors along with gate drive chips in order to boost the turn-off current by several amps. Your MOSFETs have a very high gate charge, so having two of them in parallel with only 2 amps of gate drive current may make your turn-off times very slow. --=20 Martin K. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
