NCP1653DR2G Description

Short technical summary and product information.

The NCP1653DR2G from ON Semiconductor is a compact controller designed for Continuous Conduction Mode (CCM) Power Factor Correction (PFC) boost circuits. It supports both follower boost and constant output voltage operation, with fixed switching frequencies of 67 kHz or 100 kHz. This device minimizes external component count and simplifies CCM PFC implementation.

Key electrical features include a wide operating voltage range of 8.75V to 18V and protection mechanisms such as undervoltage lockout, overvoltage protection, undervoltage protection, programmable overcurrent protection, and programmable overpower limitation. It also incorporates soft-start capability and thermal shutdown with hysteresis.

The NCP1653DR2G is suitable for applications like TV & Monitors, PC Desktop SMPS, AC Adapters SMPS, and White Goods. It is supplied in an 8-SOIC package suitable for surface mounting.

This controller is compliant with IEC1000-3-2 standards and is Pb-Free.
