NCP1653ADR2G, Power Factor Correction Controller,SOIC-8

The NCP1653ADR2G - SOIC-8 is a high-efficiency power factor correction (PFC) controller designed for use in Continuous Conduction Mode (CCM) power supplies. With a fixed switching frequency of either 67kHz or 100kHz, this controller provides excellent power factor correction, allowing for smaller and more cost-effective designs. The NCP1653 integrates advanced protection features such as programmable overcurrent protection, thermal shutdown with hysteresis, and undervoltage lockout, making it suitable for a wide range of industrial and consumer power supply applications.

This controller is ideal for use in applications such as TV and monitors, PC desktop SMPS, AC adapters, and white goods. It is capable of operating in average or peak current mode, providing flexibility in design while maintaining optimal performance. Packaged in a compact SOIC-8 form, the NCP1653ADR2G reduces the number of external components required, simplifying the design process and reducing overall costs.

With built-in overvoltage protection and soft-start capabilities, the NCP1653ADR2G ensures reliable operation and meets global energy regulations. Its high switching frequency minimizes external component size, making it a perfect choice for space-constrained designs requiring robust PFC performance.
