Please remember the input voltage must not exceed 150V, and the entire circuit is not isolated from the input high voltage, so be extremely careful…
Sir , specifications of how to design induction coil IC irs2453. .
Hello Shabbir, i do not have this circuit with me at the moment, so i am unable to provide you any help regarding this topic.
Dear Swagatham, is the current limited to the rating of zener diode or that of mosfet ?
Dear Suresh,
The maximum output current is determined by the MOSFET rating, the zener diode decides the maximum output voltage.
