FAN4800CSNY

Overview

The FAN4800CSNY is a PFC/PWM controller combination from onsemi, designed for power supplies incorporating boost PFC and PWM stages. It operates within a supply voltage range of 11 V to 22 V, with a nominal input of 15 V. The device supports an operating temperature range from -40 °C to +105 °C. It is housed in a 16-pin DIP package and utilizes through-hole mounting. This component functions as a PMIC under the FAN4800CS series.

Feature Summary

• Combines Power Factor Correction and Pulse Width Modulation control in a single integrated circuit.
• Supports both current mode and voltage mode operation for the PWM section.
• Includes built-in undervoltage protection and PFC soft-start functionality.

Applications

• Power factor correction circuits in AC-DC converters
• Universal input power supplies (85 VAC to 270 VAC)
• Systems requiring combined PFC and post-regulator control

Procurement Notes

Verify end-of-life status before procurement, as this part may be obsolete or subject to discontinuation. Confirm that the DIP-16 through-hole package aligns with existing board designs. Ensure compatibility with required thermal management for the specified temperature range. Check for available replacement alternatives if long-term supply stability is required.

Selection Notes

Select this component when a combined PFC and PWM solution is needed for through-hole applications. It is suitable for designs requiring low external component counts and integrated protection features. Consider the operating temperature range and package constraints during selection. Verify that the voltage mode or current mode requirements match the specific topology design.

Part Context

This part belongs to the FAN4800 family of power factor controllers. It is related to variants such as FAN4800A/C and FAN4801/02/02L, which offer improved performance over earlier ML4800 models. The family is designed for high-efficiency power conversion with reduced standby power consumption.

Replacement Considerations

FAN4800ANY is a documented substitute part number for this component.
