FAN4800IN_G

Overview

The FAN4800IN_G is a highly integrated Power Factor Correction (PFC) and Pulse Width Modulation (PWM) controller combination designed for power supplies utilizing boost PFC stages. Manufactured by onsemi, this component operates with a switching frequency of 84 kHz. It supports both Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) operations. The device is housed in a 16-pin DIP package, suitable for through-hole mounting. It functions within a minimum operating temperature of -40°C and a maximum operating temperature of +125°C.

Feature Summary

• Combines PFC and PWM control functions in a single integrated circuit
• Supports both CCM and DCM operational modes for flexible design
• Designed specifically for boost PFC topology applications

Applications

• Power supplies consisting of boost PFC and PWM stages
• Industrial power conversion systems
• Commercial AC-DC adapter designs

Procurement Notes

Verify the specific suffix 'G' indicates lead-free compliance and RoHS status as per onsemi documentation. Confirm the 84 kHz switching frequency specification against the official datasheet, as some sources cite 64 kHz for similar variants. Ensure the DIP-16 package matches your PCB footprint requirements. Check current availability status as distribution channels may vary.

Selection Notes

Select this component when a combined PFC and PWM solution is required to reduce board space and component count. The 84 kHz frequency offers a balance between efficiency and EMI considerations. Verify thermal management capabilities for the +125°C maximum junction temperature. Ensure the input voltage range aligns with the target application's AC line specifications.

Part Context

The FAN4800 series includes variants like FAN4800AS/CS/01S/02S, which are similarly designed for boost PFC and PWM combinations. The IN_G variant specifically denotes the DIP-16 package configuration. This family belongs to onsemi's PMIC portfolio, targeting efficient power factor correction in standard AC-DC conversion architectures.

Replacement Considerations

Direct substitutes include other FAN4800 series variants such as FAN4800ASNY or FAN4800CUM, depending on the required package type (DIP vs SOIC) and pinout compatibility. Verify functional equivalence regarding switching frequency and control loop characteristics before substitution.
