onsemi Power Factor Controller IC 130 kHz 16-Pin SOIC 20V NCP1631DR2G

The onsemi NCP1631DR2G is a high-performance Power Factor Controller IC specifically engineered for use in 2-phase interleaved power factor correction pre-converters. Operating at a switching frequency of 130 kHz, it features a compact 16-Pin SOIC package designed for surface mount applications. The device supports a supply voltage range from 10 to 20 Volts and offers robust protections including integrated overcurrent, overvoltage, undervoltage lockout (UVLO), and brown-out detection to ensure reliable operation in demanding industrial and commercial environments.

This controller facilitates interleaved PFC topology, which parallels two smaller stages instead of one large stage. Such design improves thermal distribution, allows use of smaller components, reduces EMI and RMS current through the bulk capacitor, and enhances light load efficiency. It is highly suited for slim form factor applications such as flat panel televisions and ultra-slim notebook adapters.

The NCP1631DR2G IC features a maximum sink current of 800 mA and a source current of 500 mA, with a low start-up supply current of 100 μA minimizing power consumption during initialization. It operates reliably across an industrial temperature range from -55°C to 150°C and has compact physical dimensions with a length of 10 mm and height of 1.5 mm, enabling its integration into space-constrained electronic designs.

Typical applications are power management in consumer electronics, industrial power supplies, and energy-efficient power conversion systems where precise and reliable power factor correction is critical. The device contributes to reducing power losses, improving power quality, and optimizing overall system efficiency.
