Power management integrated circuits (PMICs) play a vital role in controlling, directing and regulating the power consumed by our electronic devices. They typically contain several electronic components in one integrated circuit. One important type of PMIC is the LED driver. LEDs are commonly used in lighting applications as they provide efficient lighting with good levels of output power and efficiency. The NCP1370ADR2G is one example of an LED driver PMIC that can be used in a variety of applications. In this article, we will examine the application field and working principle of the NCP1370ADR2G.The NCP1370ADR2G is a Flyback Active Power Factor Corrector (Active PFC) LED driver. It is designed for single-stage applications and is suitable for driving high-power LED arrays that require a high-voltage input and a moderate output current. The device features an integrated flyback converter circuit and is capable of providing an adjustable, low ripple output voltage up to 1MHz. It features an Adaptive Digital Voltage Controller (ADVC) and a Peak Current Control Mode (PCCM) control loop. The device is also compatible with LED current regulation and LED dimming.The application field for the NCP1370ADR2G includes LED lighting applications such as indoor and outdoor lighting, automotive lighting, and industrial lighting applications. The device is also suitable for driving high-power LED arrays that require a high voltage input and a moderate output current. The device has a wide operating temperature range of -40°C to +85°C, making it suitable for a range of temperature environments.The working principle of the NCP1370ADR2G is based on a Flyback Active PFC architecture. The device is capable of transforming the rectified high voltage AC input into a regulated DC output. The rectified input is converted using a high frequency power switch that is connected to a high frequency transformer. The voltage sense signal is then used by the Adaptive Digital Voltage Control (ADVC) to regulate the output voltage. The output voltage is controlled by the current feedback signal provided by the Peak Current Control Mode (PCCM). In this way, the device is capable of providing a regulated output voltage with low ripple.In conclusion, the NCP1370ADR2G is a LED driver PMIC that is designed for single-stage applications and it suitable for driving high-power LED arrays. It features an integrated Flyback Active Power Factor Corrector and is capable of providing an adjustable, low ripple output voltage up to 1MHz. The device can be used in a range of LED lighting applications such as indoor and outdoor lighting, automotive lighting, and industrial lighting. The working principle of the device is based on a Flyback Active PFC architecture and is able to provide a regulated output voltage with low ripple.
