The NCV1397ADR2G is a highly integrated, high-efficiency offline two-channel power converter from ON Semiconductor. It is designed to provide two identical outputs from an AC or DC supply, and is suitable for both consumer and industrial applications. This particular model is rated for up to 96 V (with standby regulation) and provides up to 2A of output current. It is capable of working with a wide range of input voltages, from 4.5 V to 72 V, and it offers a wide range of features such as power factor correction, standby and off control, as well as over-voltage and over-current protection.The NCV1397ADR2G is an ideal choice for applications where typical AC-DC or DC-DC converter components are not available or the space for mounting components is limited. The two channel solution allows two identical output voltages from a single device, simplifying the design process. In addition, the device has a low power standby mode feature, which helps extend battery life in portable applications.The NCV1397ADR2G utilizes a unique current-mode PFC control topology that improves the efficiency and power factor of the system, making it well-suited for use in ITE and medical equipment where power factor correction is important. The device also integrates a low power standby mode which helps to reduce power consumption during standby periods, which is beneficial to applications that have a high off-state power consumption. Additionally, the device has a wide operating temperature range (from -40°C to 85°C) and high ESD immunity, making it well-suited for use in industrial applications.The working principle of the NCV1397ADR2G is quite simple. When power is applied to the device, the integrated PFC controller begins switching the primary sides’ MOSFETs, creating a controlled sinusoid across the primary side inductor. The controller monitors and regulates the voltage and current flowing through the primary side inductor and outputs a sinusoidal current with an associated sinusoidal voltage across the secondary side transformers. The controller also has built-in overload and overvoltage protection to keep the system safe and protect the components from excessive current and voltage.In summary, the NCV1397ADR2G is a high-performance and cost-effective two channel power converter from ON Semiconductor. It is designed to provide two identical outputs from an AC or DC supply and is suitable for both consumer and industrial applications. The device has a wide operating temperature range and high ESD immunity, making it suitable for use in harsh environments. It utilizes a unique current-mode PFC control topology that improves the efficiency and power factor of the system, making it ideal for use in ITE and medical equipment. Furthermore, it has built-in overload and overvoltage protection to keep the system safe.
