The NCP1249DD65R2G has several features that make it useful for a variety of applications. It has a wide input voltage range of 90V to 265V AC, adjustable output voltage range of 7V to 18V, and output current adjustable from 5mA to 60mA. Additionally, it has low standby power, low input current, wide VCC operating range, and protected frequency jittering.

The NCP1249DD65R2G utilizes current-mode control to regulate the output voltage. This type of control uses a comparison of the reference voltage and an internal error amplifier to set a voltage level at the input of the oscillator. The comparator then monitors the voltage of the output winding and adjusts the duty cycle of the power switch to maintain the output voltage. In this way, the output voltage is regulated according to the error voltage.

The NCP1249DD65R2G has additional features that make it useful in certain applications. It has a power-good output that indicates when the power supply is in the safe operating range. It also has an internal soft-start that limits the inrush current during start-up and a power-on reset that prevents damage in the event of a power failure. Additionally, the NCP1249DD65R2G provides a low-power-loss shutdown feature that increases efficiency by reducing power losses when the circuit is not in use.

In summary, the NCP1249DD65R2G is an integrated offline switcher controller with fixed-frequency, current-mode control and a high voltage integrated power mosfet.
