LM358 can also implement DCDC function!

Common dcdc internal structure diagram and simple analysis LM358 MPPT circuit schematic diagram is as follows (only screenshots are available) PCB and 3D effects (only screenshots are available) Output hardware closed-loop brief description Input hardware closed-loop brief description General description
1: Please forgive me for inappropriate description.
2: The PWM period is generated by the charge and discharge of the sampling resistor and the sampling capacitor. The PWM period is also different (unstable) with different voltages.
     This method is cleverly used to replace the triangle wave generator in DCDC and compare the PWM output.
3: There is a voltage difference between the output of LM358 and VCC, but it will not be affected when using a Pmos tube.
4: Input control and output control need to control Pmos to turn off at the same time. If any conditions are not met, MOS will be turned off, so the method of diode + pull-down resistor is used.
     This is also a lazy approach and is only suitable for low frequency situations, but it also complies with [slow open] , quick off] use?
5: Maybe there will be another iteration in the future?
6: I have been homeless for many years. Now I can go home and lie down. If you can, watch my videos and order some eggs.

7: Actually, I don’t have a network at home, so I’m sorry that I didn’t use Lichuang EDA for development. . . smms…
