I often see schematics of basic buck converters. The majority of these schematics use a P-Mosfet as high side switch.
Why is this design preferred over a low side, N-Mosfet buck converter?
Would this design work?
The load is a 12V Fan, 3.6W
The Mosfet would be driven directly from the microcontroller in PWM, 5V logic, 32 Khz carrier frequency.
