PMIC (Power Management Integrated Circuit) AC/DC converters, also known as Offline Switchers, are electronic components used to make a wide variety of electronic products capable of running on mains power. The NCpower NCP1339JDR2G is one such component, and it is specifically designed for applications in mobile devices, home appliances and other low-power appliances. This article will discuss the component’s application field and working principle.

NCP1339JDR2G is a 60V, 1A offline switcher AC/DC converter that can be used in a broad range of applications. It is designed to deliver a regulated output current with very little noise and ripple, while also providing excellent power efficiency. Its wide input voltage range makes it suitable for powering a variety of applications including smartphones, tablets, medical equipment, industrial equipment, consumer products and more. Furthermore, the component is able to detect line voltage changes and adjust the output accordingly.

The NCP1339JDR2G is equipped with a high switching frequency and a unique PFC (Power Factor Correction) methodology for improved output efficiency. As for operation safety, the component integrates a wide range of protection features such as over/under voltage protection, over-temperature protection, and over-current protection. On the communication interface side, the component supports I2C communication interface for enhanced load control. All of these features make it an ideal choice for AC/DC conversion.

The NCP1339JDR2G works by feeding a voltage source, such as mains power, into the primary side of a switching regulator, which then outputs a regulated DC voltage or current to use as the power source. This is done by using a transformer to transform the incoming AC voltage into a voltage that is suitable for the indicator LED. After the LED is powered, the transformed voltage is adjusted to an appropriate level by using a linear regulator, or a switching regulator to convert the unregulated AC voltage into a regulated DC voltage. The output is then used to power the DC loads, such as a mobile device or other electronics.

In summary, the NCP1339JDR2G is an ideal AC/DC converter for powering low-power electronic products. It offers high power efficiency, excellent line voltage stability, and a wide range of protection features, as well as an I2C communication interface for enhanced load control. The component works by taking in an AC voltage source and transforming it into a regulated DC voltage for powering the DC load. Therefore, the NCP1339JDR2G is a great choice for powering various mobile devices and other electronics.
