ON Semiconductor NCP1342 Flyback Controller
ON Semiconductor NCP1342 is a highly integrated quasi−resonant flyback controller for that simplifies off-line power converter design. The controller integrates a high-voltage start-up circuit with brownout protection and active X2 capacitor discharge functionality to reduce standby power consumption compared to resistive alternatives, with no-load power below 30mW.
This device also features rapid frequency foldback and skip mode operation for increased efficiency at light loads, with quiet-skip technology to prevent audible noise. The NCP1342 operates from a 9V to 28V supply and offers many protection features for robust operation, including non-dissipative overpower protection, over temperature shutdown, and overvoltage and overcurrent protection.
