ON Semiconductor NCP1280DR2

NCP1280DR2 Overview
ON Semiconductor is a well-known brand in the electronics industry, especially in the field of power management. One of their popular products is the PMIC - AC DC Converters, Offline Switchers chip. This chip falls under the category of PMIC - AC DC Converters, Offline Switchers, which are essential components in power supply systems. These chips are responsible for converting the alternating current (AC) from the main power source into direct current (DC) that can be used by electronic devices. The ON Semiconductor PMIC chip is designed for surface mount installation, making it suitable for compact and space-constrained applications. It can operate within a wide temperature range of -40°C to 125°C, providing reliable performance even in harsh environments. The terminal finish of this chip is Tin/Lead (Sn/Pb), which ensures a secure and durable connection between the chip and the circuit board. This PMIC chip has a single function, making it a cost-effective and efficient solution for power management. Its base part number is NCP1280, which is a unique identifier for this specific chip model. It has a pin count of 16, which indicates the number of connections required for proper functioning. The output voltage of this chip is 18.3V, which is suitable for a range of electronic devices. The control mode of this chip is CURRENT-MODE, which means that it regulates the output voltage by controlling the current flow. This mode of operation ensures stability and reliability in the power supply system. The switcher configuration of this chip is PUSH-PULL, which is a common design in AC DC converters. It uses a pair of switches to alternate between positive and negative cycles of the input voltage, resulting in a smooth and continuous output. One notable feature of this ON Semiconductor chip is that it does not have internal switches. This means that external switches need to be connected for the chip to function correctly. However, this design allows for more flexibility and customization in the power supply system. In conclusion, the ON Semiconductor PMIC - AC DC Converters, Offline Switchers chip offers a reliable and efficient solution for power management. Its surface mount installation, wide operating temperature range, and current-mode control make it suitable for various applications. With its push-pull switcher configuration and external switch requirement, this chip provides flexibility and customization options for power supply systems.
