Overview
The FAN4800IN is a highly integrated Power Factor Correction (PFC) and Pulse Width Modulation (PWM) controller combination designed for offline power supplies. It features a fixed switching frequency of 64 kHz and supports Through-Hole installation in a DIP-16 package. The device operates within a temperature range of -40°C to +125°C. It integrates boost PFC and PWM control functions into a single component, offering low startup current characteristics suitable for energy-efficient designs.
Feature Summary
- Combines PFC and PWM control functions in a single integrated circuit
- Optimized for offline flyback converter applications
- Features low startup current for improved efficiency
Applications
- Offline flyback converters
- Power factor correction circuits
- General purpose power supply designs
Procurement Notes
Verify the specific suffix IN against official onsemi documentation to confirm pinout and electrical specifications. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the DIP-16 through-hole package matches your PCB layout requirements before ordering.
Selection Notes
Select this component when a combined PFC and PWM solution is required for offline topologies. The fixed 64 kHz frequency simplifies magnetic component design. Verify that the operating temperature range meets your environmental constraints and that the through-hole package is compatible with your manufacturing process.
Part Context
The FAN4800 series includes variants such as AS, CS, and IMX, differing primarily in package type and switching frequency ranges. The IN variant specifically denotes the through-hole DIP-16 configuration with a 64 kHz fixed frequency. This places it within the broader family of integrated power management ICs from onsemi.
Replacement Considerations
Check for direct cross-references in onsemi's obsolescence notices. Other FAN4800 variants like FAN4800ASNY share similar functionality but differ in package and frequency. Verify pin compatibility before substituting.
