Stage light, power circuit board, tcp249yn6 pin, integrated circuit principle
You're wrong. You're TOP249YNThat's probably the principle:220V TOP249 D AC rectifier filter to pin and D pin through the buck converter for low voltage supply integrated itself to work, is to start the integration, making D, S pin high frequency switch, so that the secondary winding of the transformer to obtain magnetic field, magnetic and electrical conversion, and then through the rectifier filter regulator output to LED. There is a feedback loop in the middle to ensure that the circuit can work properly.
