Hi guys,
I want to make simple DC-DC converter with these characteristics:
V in: 28V
V out: 14V 3A
The converter must be without sink, so i use external P-MOS transistor with low Rds - Si7463.I tried circuit without driver for MOS transistor, but it is heated for a very short time.So i decided to put driver, but i don't know how to wire, because the input voltage is 28V more than MAX Vgs on transistor.
Thank's advance!
