FAN9611MX

The FAN9611MX is a highly efficient, dual-interleaved, boundary-conduction mode (BCM) power factor correction (PFC) controller. It is designed to improve power factor and reduce total harmonic distortion in AC-DC power supplies. The FAN9611MX operates with continuous conduction mode (CCM) and provides excellent efficiency by minimizing switching losses. Its interleaved structure ensures reduced input and output ripple currents, which results in lower electromagnetic interference (EMI) and smaller passive components.
The device features advanced protection mechanisms, such as overvoltage protection (OVP), under-voltage lockout (UVLO), and overcurrent protection (OCP), enhancing system reliability. It also includes a programmable switching frequency and a highly accurate multiplier. The FAN9611MX is typically used in applications like power supplies for computers, televisions, and other consumer electronics requiring efficient power conversion and PFC capabilities. Its compact MX package and robust feature set make it a suitable choice for high-density applications where space and efficiency are critical.
