BUCK converter is one of the most common design components in the design of some high-power switching power supply circuits. It has the advantages of high conversion rate and high adaptability, which can greatly help engineers' product design and development. This article teaches you to make a buck converter.

Control loop design

The schematic diagram of the control loop is shown below:

Calculation of main loop parameters

The input voltage is chosen to be 20V. Since the input Vs = 20V, the output V0 = 10V, so D = 1/2. Since the switching frequency is 30KHz.

Since the instantaneous current (maximum current) cannot exceed 0.5A,

You can get L>=3.3*10^3H, so the inductor 681 is selected again.

Let R>=40, so choose a resistor of 47Ω.

Current is required to be continuous, so
