Make sure the inductance between the source and the common for the FET drivers is minimized (in the high current path). Are you using a series resistor between the driver outputs and the FET gates? If not, something like 10-20R can be a good idea. --sp --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
