Add To BomNCP1251ASN65T1G General Description
The NCP1251ASN65T1G is an integrated circuit (IC) manufactured by ON Semiconductor. It belongs to the NCP1251 family of PWM (Pulse Width Modulation) controllers specifically designed for offline power supplies. This IC operates with a fixed switching frequency and features a high-voltage start-up current source. With a wide input voltage range, typically from 85V AC to 265V AC, it can accommodate various input sources. The NCP1251ASN65T1G integrates several protection features, including overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown, enhancing system reliability. This device is housed in a small SOT-223 package, making it suitable for space-constrained applications. Its precise regulation and efficiency make it ideal for use in low-power, non-isolated flyback converters found in various consumer electronics, such as chargers, adapters, and auxiliary power supplies. Additionally, its low standby power consumption contributes to energy-efficient designs
