PMIC, or Power Management Integrated Circuit, is an essential component of modern electrical systems. The NCP1077BBP065G is a high efficient AC/DC converter with offline switcher. It is designed to optimize the power efficiency of electronic devices by solving the problem of high power loss in traditional linear ICs. In this article, we will discuss the application field and working principle of the NCP1077BBP065G.

The NCP1077BBP065G is primarily used in applications which require high power conversion efficiency over a wide range of input voltages. It is suitable for medical, automotive, consumer and industrial applications. The NCP1077BBP065G works by rectifying an AC supply to a DC output that is injected into a buck converter. The buck converter is designed to ensure a high efficiency output, which allows for a small voltage drop across the switching element, reducing power losses. The buck converter then feeds the DC output to a Flyback converter, which is used to generate the desired output voltage and current.

The NCP1077BBP065G uses a combination of PWM and Linear Regulation for maximum efficiency. In PWM mode, the NCP1077BBP065G utilizes a high frequency pulse width modulation to control the output current. This provides a better efficiency than linear mode, as the switching elements are working in the linear range, resulting in less power losses. The NCP1077BBP065G also incorporates a Linear Regulation setting, which is used when the output voltage is low, allowing it to have high output precision and stability.

The NCP1077BBP065G also provides an additional level of protection by integrating a variety of safety features. It includes over-voltage, over-current, continuous current sense, and thermal shutdown to prevent damage to the device and other components in the system. It also has a system reset pin for fault recovery, and EMI filtering for better noise immunity.

In conclusion, the NCP1077BBP065G is an ideal choice for applications requiring high power conversion efficiency over a wide range of input voltages. Its combination of PWM and Linear Regulation, as well as its extensive safety features, make it a great choice for any system.
