FAN4800ASNY

Overview

The FAN4800ASNY is a power factor correction and PWM controller combo IC manufactured by onsemi. It integrates PFC and PWM control functions in a single package, designed for AC-DC conversion applications. The device operates within an input voltage range of 11V to 26V and supports a switching frequency between 240kHz and 268kHz. It features a maximum power dissipation of 800 mW and includes two output interfaces. The component is housed in a 16-pin PDIP package with dimensions of 19.69 mm length, 7.11 mm width, and 4.95 mm height. It is rated for operation from -40°C to +105°C.

Feature Summary

• Integrates Power Factor Correction (PFC) and Pulse Width Modulation (PWM) control functions into a single controller unit.
• Supports dual output interfaces for combined power management tasks.
• Operates reliably across a wide industrial temperature range from -40°C to +105°C.

Applications

• AC to DC single-output power supplies
• Uninterruptible Power Supply (UPS) systems
• Forward converter topologies

Procurement Notes

Verify the specific suffix ASNY against official onsemi documentation to confirm pinout compatibility and thermal characteristics. Check current availability status as distribution channels may vary. Ensure the procurement source provides valid RoHS compliance certificates and original manufacturer traceability records before finalizing orders.

Selection Notes

Select this component when a combined PFC and PWM solution is required for forward converter designs. Consider the 16-pin DIP package for through-hole mounting requirements. Evaluate the 240kHz to 268kHz switching frequency range against electromagnetic interference constraints. Confirm that the 11V to 26V supply range aligns with the auxiliary power circuit design.

Part Context

The FAN4800 series represents a family of integrated controllers combining PFC and PWM functionalities. This specific model utilizes a PDIP-16 package suitable for general-purpose power electronics. It serves as a compact alternative to discrete control solutions, reducing external component count while maintaining high efficiency in AC-DC conversion stages.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with legacy ML4800 or FAN4800 designs only if official replacement guides are consulted. Do not assume functional equivalence with other series members without detailed datasheet comparison.
