FAN4801NY

Overview

The FAN4801NY is a highly integrated Power Factor Correction (PFC) controller from onsemi, designed for power supplies combining boost PFC and PWM stages. It operates with an average current mode control scheme at a switching frequency of 64 kHz. The device features a low startup current of 30 µA and supports operation within a temperature range of -40°C to +105°C. Packaged in a 16-pin DIP format for through-hole mounting, it serves as a specialized solution for efficient power management applications.

Feature Summary

• Highly integrated design specifically engineered for combined boost PFC and PWM power supply architectures
• Utilizes average current mode control to optimize power factor correction performance
• Features ultra-low startup current consumption to enhance energy efficiency during activation

Applications

• Power supplies utilizing combined boost PFC and PWM topologies
• Industrial power conversion systems requiring high integration
• Energy-efficient electronic equipment power management

Procurement Notes

Verify component status carefully as the FAN4801NY is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary markets if sourcing for replacement designs. Ensure compatibility with existing PCB footprints and validate that alternative components meet all electrical specifications before implementation in new production runs.

Selection Notes

Select this component when designing power supplies that require a single IC solution for both PFC and PWM functions. It is suitable for applications needing average current mode control with a fixed 64 kHz switching frequency. Consider its through-hole DIP-16 package for prototyping or specific mechanical constraints. Evaluate its low startup current requirement against system power budget needs.

Part Context

The FAN4801NY belongs to the FAN4800/4801 family of power management ICs from onsemi. This series is tailored for integrated power solutions, distinguishing itself by combining multiple control functions into one package. It complements other devices like the FAN4800CNY, offering similar integration levels for different specific control requirements within the same product line.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineers must identify functional equivalents based on pin compatibility and electrical parameters from other manufacturers or newer generations of onsemi products.
