The fourth pin of the chip U1 is electrically connected to the other end of the capacitor C2, the anode of the diode D1 and the second pin of the chip U2 respectively.

[0037] From the above description, it can be seen that chip U1 is a high-performance capacitor AC-DC converter, and chip U2 is a DC-DC converter. The AC-DC converter converts AC into DC, and the DC-DC converter filters out common-mode interference between different grounds. Both the AC-DC converter and the DC-DC converter are isolated converters, that is, the input and output are isolated and not grounded. At the same time, there is an additional protection design at the input end of the power supply circuit. The varistor RV1 is set to protect the power supply from damage in the event of a lightning surge. The capacitor C1 and the inductor L form an EMC protection circuit to ensure that the product does not pollute the power grid and is a reliability design for the electrical appliance.

After the 5V voltage is filtered by the electrolytic capacitor CE1 and the capacitor C3, the 5V voltage is input to the chip U3, and the chip U3 converts it into a 3.3V voltage output. The 3.3V voltage is filtered and given to the back-end circuit.
