The ZCD circuit monitors the core demagnetization of the flyback transformer through an auxiliary winding. When the secondary-side current drops to zero, the voltage on the ZCD pin falls below an internal threshold, instructing the GATE driver to turn the external MOSFET back on. This ensures seamless Boundary Conduction Mode operation. 5. Built-In Protection Features
