Hi,
I want to build a buck converter. I use the IR2113 gate driver but the voltage of VB and VS Ho, HL is zero. what is my problem. I think my connection it's not correct.
I cant see any feedback.
Also, why is cout got esr = 1ohm
HO is referenced to VS but I cant see how that works in yor schem.
VB is the high side drive volts for HO but again I cant see how that works in your schem.
ir2113 is a half bridge hi and lo driver, and isnt meant for a buck.
Just use a high side bootstrap driver...is it LTC4440 by linear.com?, or something like that.
I cant see a ground on your power circuit
