The NCP1240GD065R2G is a fixed-frequency current-mode offline flyback controller from ON Semiconductor. It operates at a switching frequency of 65 kHz and accepts an input voltage range of 9.3V to 28V. The controller is designed for isolated flyback topologies and includes a comprehensive set of protection features.
Key features include frequency foldback then skip mode for light-load efficiency, timer-based overload protection, high-voltage current source for startup, brown-out detection, dynamic self-supply, and frequency modulation for softened EMI signature. The device also provides adjustable overpower protection, a latch-off input, and soft-start with a 10 ms timing.
The controller is housed in a 7-pin SOIC package (SOIC-7) and has an operating junction temperature range of -40°C to 150°C. It does not include an internal power switch, requiring an external MOSFET for power conversion.
