The NCP1653PG from ON Semiconductor is a versatile and robust active power factor controller designed for use in compact and efficient power supplies. This integrated circuit is tailored to enhance power factor correction (PFC) in a wide range of applications, including but not limited to, consumer electronics, office equipment, and industrial systems. With its ability to deliver high power efficiency and reduce harmonic distortion, the NCP1653PG is an ideal choice for designers looking to meet stringent energy-saving standards.
The NCP1653PG operates in Continuous Conduction Mode (CCM), which makes it suitable for applications that require a high power factor and low electromagnetic interference (EMI). Its built-in features include soft-start, which prevents inrush current at startup, and a brown-out detection function that ensures stable operation under varying input voltage conditions. Additionally, the device offers overvoltage protection, under-voltage lockout, and overcurrent protection, safeguarding the power supply and the end equipment from various electrical anomalies.
This power factor controller is designed with a minimal external component count in mind, simplifying the design and reducing the overall bill of materials. Its frequency modulation capability helps to further minimize EMI, facilitating compliance with international EMI regulations. The NCP1653PG is available in a compact 8-pin PDIP package, making it easy to integrate into various PCB layouts without taking up significant space.
