The NCP1216AD133R2 is an integrated circuit (IC) component designed for offline flyback converters in AC-DC power supplies. It is manufactured by On Semiconductor and offers a range of key features that make it suitable for various applications.
One of the prominent features of the NCP1216AD133R2 is its high level of integration. It combines a power factor correction (PFC) controller, a controller for the resonant stage, and a power MOSFET driver in a single package. This integration not only reduces the component count but also simplifies the design process, making it easier to implement in power supply circuits.
The IC operates in a critical conduction mode (CrM) for power factor correction, which helps achieve a high power factor and low harmonic distortion. It supports continuous and discontinuous conduction modes with a fixed frequency operation, allowing flexibility in designing power supplies for different loads and output power. Moreover, the NCP1216AD133R2 offers a wide operating input voltage range, making it suitable for universal mains voltage applications.
To ensure reliable and efficient operation, the IC includes a set of protection features. It incorporates overcurrent protection, overvoltage protection, and over-temperature protection mechanisms. These safeguards prevent damage to the device and the overall power supply system in case of abnormal operating conditions, ensuring a high level of system safety and reliability
