DIY flyback power supply on the CR6850

Hi all! In today's video I will tell you in detail and show you how to make a powerful flyback power supply with your own hands. It is assembled on a CR6850 chip. This is a compact but reliable PWM controller with adjustable frequency, high efficiency and low idle current consumption. The power of the converter is 20 watts, the output voltage is 5 volts, and the current it can consistently deliver for a long time is 4 amperes! In extreme mode, it can produce more, but not for long. I present this video as a technical guide to the CR6850; here I have collected the most important information about its circuitry and operating principle. In the future, I will build even more interesting blocks based on it, but I will not return to a detailed explanation in them.
