I've been designing a non-inverting buck-boost converter with a low side switch (see image) for use as an MPPT controller. In simulation, it appears to buck and boost voltage adequately, but when prototyping the circuit, there is no voltage output and the switch(N-channel MOSFET) noticeably heats up. Could this be due to inductor saturation, incorrect switching or some other factor?
