The NCP1240 is a new fixed−frequency current−mode controller featuring Dynamic Self−Supply. This function greatly simplifies the design of the auxiliary supply and the VCC capacitor by activating the internal startup current source to supply the controller during start-up, transients, latch, stand-b • Frequency foldback and skip mode\n• Optimized efficiency across the entire load range\n• Timer-based overload protection with latched (A version) or auto-recovery (B version) operation\n• Protection against overcurrent and short circuit\n• High-voltage startup with dynamic self supply\n• Simplifie;
