FAN4802NY

Overview

The FAN4802NY is a Power Factor Correction (PFC) controller manufactured by Fairchild Semiconductor, now part of onsemi. It operates in average current mode with a fixed switching frequency of 64kHz. The device supports a supply voltage range of 11V to 22V and functions within an operating temperature range of -40°C to 105°C. It is housed in a 16-SOIC package with a width of 3.90mm. The IC features a low startup current of 30 µA and includes a post-regulator for enhanced performance.

Feature Summary

Implements average current mode control for precise power factor correction.
Integrates a post-regulator to improve transient response and regulation.
Operates at a fixed 64kHz switching frequency to optimize EMI filtering.

Applications

Offline power supplies
AC-DC converters
Power factor correction stages

Procurement Notes

Verify the manufacturer status as Fairchild Semiconductor products are managed under onsemi. Confirm the specific suffix 'MY' or 'NY' matches the required package and temperature grade. Check RoHS compliance status against current environmental regulations. Ensure the component is available from authorized distributors given potential lifecycle changes.

Selection Notes

Select this component for applications requiring average current mode PFC control. The fixed 64kHz frequency simplifies magnetics design. Verify that the 11V to 22V supply range aligns with the system's auxiliary power requirements. Consider the 16-SOIC package constraints for PCB layout and thermal management.

Part Context

The FAN4802 series belongs to a family of PFC controllers designed for high-efficiency power conversion. Variants like FAN4802MY and FAN4802LMY share similar electrical characteristics but may differ in packaging or lifecycle status. This specific model represents a standard offering for general-purpose PFC applications.

Replacement Considerations

Check for direct substitutes within the FAN4802 family such as FAN4802MY. Verify pin compatibility and electrical specifications before substituting with other PFC controllers from different manufacturers.
