switch mode power supply What does frequency foldback do in a switching regulator

When VOUT is very low during start-up or a short-circuit fault on the output, the switching regulator must operate at low duty cycles to maintain the power switch current within the current limit range, since the inductor current decay rate is very low during switch off time. The minimum on-time limitation may prevent the switcher from attaining... .
schematics Buck switching regulator based on ATtiny84a -- please critique!

The microcontroller won`t be able to drive the gate of Q1 very hard (usually GPIO pins can only source a few milliamps) so your turn-on and turn-off will be very slow. This will limit how well your high-side switch will behave. You don`t have a gate-to-source resistor on Q1, so you`re solely dependent on the GPIO keeping the MOSFET on or off. If t .
power Switching Between Two Voltage Supplies
