working on efficient power between buck and linear regulators. 24v into a divider for the 555 timer. 555 sets a frequency output, which goes into the NPN transistor. NPN is used for Fet driving circuit to drive the N-Channel mosfet. We have 24v's applied to the gate and the frequency attached to the gate. With that we get a set frequency pattern for the Buck Circuit, brining voltage down to 17ish volts. With current being limited by the buck circuit, we can now safely use a zener and a op amp to keep output voltages consistent 15v.
