Abstract: The present invention discloses a switching power supply, comprising a primary-side control circuit, a secondary-side control circuit, a controller, and a millimeter wave transceiver, all integrated onto a single chip. The controller connects to the primary-side control circuit via the millimeter wave transceiver and is also connected to the secondary-side control circuit. The isolation provided by the millimeter wave transceiver ensures the required safety isolation distance between the primary and secondary sides, thereby achieving a fully integrated single-chip design. This monolithic design not only simplifies the circuitry and reduces the size of the power supply, but also lowers EMI interference. Moreover, control for the primary side is directly generated by the controller, with signals transmitted and received via the millimeter wave transceiver. This approach greatly improves the speed of signal transmission and reception, leading to low latency and high operational efficiency.
