    產(chǎn)品信息

    The NCP1340 is a highly integrated quasi?resonant flyback controller suitable for designing high?performance off?line power converters. With an integrated active X2 capacitor discharge feature, the NCP1340 can enable no?load power consumption below 30 mW. The quasi?resonant current?mode flyback stage features a proprietary valley?lockout circuitry, ensuring stable valley switching. This system works down to the 6th valley and transitions to a frequency foldback mode to reduce switching losses. As the load decreases further, the NCP1340 enters quiet?skip mode to manage the power delivery. To help ensure converter ruggedness, the NCP1340 implements several key protective features such as internal brownout detection, a non?dissipative Over Power Protection (OPP) for constant maximum output power regardless of input voltage, a latched over voltage and NTC?ready over temperature protection through a dedicated pin, and line removal detection to safely discharge the X2 capacitors when the line is removed.
