I designed this circuit hacheur.jpg and I will use this method to control my pump 12V (in the place of an other circuit which I posted two weeks ago...) from the STM32 microcontroller which give a PWM 3.3V in the input.
The problem now is : If I put the supply +12V, the IR2110 become very hot and it is destructed!!! the IRF350 is also very hot and I haven't the PWM (12V) in the output !!!!
Can you help me and tell me what's the problem and what can I modify ???
