ONSEMI NCP1246BLD065R2G Flyback Power Controller

The NCP1246BLD065R2G is a fixed-frequency, current-mode controller designed for flyback converters, optimizing light load efficiency and stand-by power. It features a dynamic self-supply, brown-out detection, built-in fault timers, and low no-load power consumption. Equipped with frequency jittering, soft-start, slope compensation, and overcurrent protection, this device ensures robust power supplies with enhanced EMI performance and safety features. Ideal for offline power adapters and electronic power supplies requiring high efficiency, reliable overload protection, and minimal standby power. The controller operates up to 65 kHz, with options for 100 kHz, and integrates comprehensive safety mechanisms including thermal shutdown and X2 capacitor discharge.
