I am using LT3845 in a 12V to 100V Boost configuration. I have a few questions:
1. I connected the TG to the controlling gate and the BG I shorted to ground thru a 10kΩ resistor. I am using a diode as the secondary switch. This circuit (attached) seems to be working. The question I have is: Can I use the BG to connect to an NMOS? if not, why doesnt it work?
2. Where should I connect the sense resistor? before the inductor, on the drain of the controlling nmos or on the source of the controlling nmos.
3.Do you have an average model I can use to check for stability in a boost configuration?
