FAN9611MX

Overview

The FAN9611MX is an interleaved dual Boundary-Conduction-Mode (BCM) Power Factor Correction (PFC) controller manufactured by onsemi. It operates with a switching frequency of 525 kHz and supports input voltages between 9 V and 18 V, with a nominal supply of 12 V. The device functions within a temperature range of -40°C to +125°C and consumes 80 µA of operating supply current. It is housed in a 16-pin SOIC package designed for surface mount installation.

Feature Summary

Implements interleaved dual BCM control architecture for high-efficiency power factor correction
Supports parallel boost power trains operating 180 degrees out of phase
Designed for thin form-factor applications requiring compact power solutions

Applications

300W interleaved PFC evaluation systems
High-density DC-to-DC power conversion stages
Compact power supplies requiring thin profile designs

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with onsemi or authorized distributors before integration. Confirm that the SOIC-16 package dimensions match your PCB footprint requirements. Ensure thermal management strategies account for the specified operating temperature range during final design validation.

Selection Notes

Select this component when designing interleaved PFC topologies requiring boundary conduction mode operation. It is suitable for applications needing dual-phase synchronization to reduce input ripple. Consider the 525 kHz switching frequency for magnetic component sizing. Verify compatibility with external MOSFETs and inductors for the target power level.

Part Context

This part belongs to the FAN9611 series of power management ICs focused on power factor correction. It complements other onsemi components like the FAN9612 controller for higher power levels. The device integrates voltage-mode control techniques to optimize efficiency in AC-DC conversion stages.
