NCP1654BD65R2G Power Factor Controller IC – CCM PFC – OnSemi – SOIC-8

The NCP1654BD65R2G from ON Semiconductor is a high-performance Continuous Conduction Mode (CCM) Power Factor Controller IC designed for PFC step-up pre-converter applications. Operating in fixed-frequency PWM mode with real-time current control, this controller enhances power quality and meets international IEC61000-3-2 standards for harmonic performance.

Housed in a compact SOIC-8 package, the NCP1654BD65R2G simplifies the design of efficient PFC circuits, reducing the number of external components required. The IC features strong ±1.5A gate-drive capability, enabling fast and reliable switching of high-power MOSFETs or IGBTs. With its low startup and shutdown currents, integrated oscillator options, and multiple protection mechanisms, the NCP1654 provides a robust and energy-efficient solution for modern power supply designs.

Ideal for power adapters, industrial power supplies, LED drivers, consumer electronics, and any system requiring high-efficiency front-end PFC.
