FAN4800IMX

Overview

The FAN4800IMX is a Power Factor Correction (PFC) and Pulse Width Modulation (PWM) combo controller manufactured by onsemi. It integrates CCM/DCM PFC control with PWM functionality in a 16-SOIC package. The device operates with a switching frequency range of 66 kHz to 84 kHz and supports a supply voltage of 11 V to 16.5 V. It functions within an operating temperature range of -40°C to 125°C and features a typical startup current of 100 µA.

Feature Summary

• Integrates continuous conduction mode (CCM) and discontinuous conduction mode (DCM) PFC control with PWM generation.

Applications

• Power supplies utilizing boost PFC and PWM topologies

Procurement Notes

Verify component authenticity through authorized channels, as the part status is listed as obsolete. Confirm package integrity for the 16-SOIC form factor and ensure compliance with RoHS standards prior to integration into final designs.

Selection Notes

Select this component for designs requiring integrated PFC and PWM control in a surface-mount format. Ensure the application supports the specified 66 kHz to 84 kHz switching frequency range and accommodates the 11 V to 16.5 V supply voltage requirements.

Part Context

This component belongs to the FAN4800 series of power management ICs designed for high-efficiency power conversion. It serves as a combined solution for power factor correction and pulse width modulation, replacing older discrete or single-function controller approaches in compact power supply architectures.
