FAN4802LNY

Overview

The FAN4802LNY is a highly integrated Power Factor Correction (PFC) and Pulse Width Modulation (PWM) controller combination designed for power supplies utilizing boost PFC stages. It operates at a fixed switching frequency of 64 kHz and supports average current mode control. The device is housed in a 16-pin DIP package with through-hole mounting. It functions within a supply voltage range of 11V to 22V and dissipates up to 800 mW. The operational temperature range spans from -40°C to 105°C.

Feature Summary

• Integrates PFC and PWM controllers into a single component to minimize external component count
• Supports versatile protection and compensation mechanisms
• Utilizes average current mode control for the PFC stage

Applications

• Power supplies consisting of boost PFC and PWM stages
• General purpose AC-DC conversion systems

Procurement Notes

Verify the specific suffix 'LNY' against the manufacturer's official datasheet to confirm pinout, package dimensions, and electrical characteristics match the design requirements. Confirm RoHS compliance status as per the latest documentation. Note that this component may be designated as Not Recommended for New Designs by the manufacturer; evaluate long-term availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when a combined PFC and PWM solution is required to reduce board space and component count. Ensure the application utilizes a boost PFC topology compatible with average current mode control. Verify that the operating environment falls within the specified -40°C to 105°C temperature range and that the 16-pin DIP package fits the mechanical constraints.

Part Context

The FAN4802LNY belongs to the FAN4800/4801/4802 family of power factor correction controllers manufactured by Fairchild Semiconductor. This family is characterized by high integration levels, combining PFC and PWM functionalities to simplify power supply designs. The LNY suffix typically denotes a specific package variant, such as the 16-pin DIP, distinguishing it from SOP or other package options within the same functional family.
