Hi all
I have made a dc to dc converter with the pulse width modulator IC (SG3524) , the output of this IC goes to the N-channel Mosfet driver IC ( IR2117) and then I have used the N-channel mosfet with the buck converter configuration. now my problem is that the output voltage of the buck converter is not stable . so, please help me , I am also uploading the circuit diagram .
