are there any specific tips or precautions to be taken when designing a buck converter with a 10 A output? for example, are there stages needed? or extra safety circuits needed anywhere? or can a basic configuration work just fine?
ive constructed one and im using a UC3843 PWM controller for the gate drive of the mosfet and my inductor is a ferrite core toroid awg12 magnet wire. i selected the mosfet and diode to be adequate for 10 A. is there anything else i need to consider? i really need help. i get stuck at 3 A load. further than that, the supply voltage starts to drop and apparently gets drawn into the circuit. my design was based on these specs: Vin min = 30V, Vin max = 60V, Vout = 24V Iout max = 10A.
