DIY flyback power supply on the CR6850

############################# Video Source: www.youtube.com/watch?v=MDvLD8pA6GQ

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. • Cloud link to the PCB file for the program Sprint-Layout: • https://cloud.mail.ru/public/THTV/57S... • Download program SprintLayout: • https://cloud.mail.ru/public/rxsa/yYv... • CR6850 chips can be purchased here: • http://alii.pub/67qj6l • Tin suction can be purchased here: • http://alii.pub/67qj3v • 2N60 transistors can be purchased here: • http://alii.pub/67qjah • TL431 chips can be purchased here: • http://alii.pub/67qj8j • PC817 chips can be purchased here: • http://alii.pub/67qj7y • 20100ct diodes can be purchased here: • http://alii.pub/67qiuj • The LCR-T4 radio component tester can be purchased here: • http://alii.pub/67qiyt • • • • #circuit #led #diy #electronics #своимируками #светодиод #электроника #howtomake #powersupply #smps
