Overview
The FAN4800IM is a Power Factor Correction (PFC) controller manufactured by onsemi, designed for continuous conduction mode (CCM) and discontinuous conduction mode (DCM) applications. It operates within a supply voltage range of 11V to 16.5V and supports switching frequencies between 66kHz and 84kHz. The device features an average current startup of 100 µA and is housed in a 16-SOIC package with a width of 7.50mm. It functions across an operating temperature range of -40°C to 125°C.
Feature Summary
- Supports both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) operation for versatile power factor correction designs.
Applications
- Power factor correction systems requiring CCM/DCM control
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package type and temperature rating. Check for obsolescence notices as this part may be discontinued. Ensure compliance with RoHS and REACH regulations relevant to your region. Validate that the ordering code aligns with the exact electrical specifications needed for the design.
Selection Notes
Select the FAN4800IM when designing PFC circuits that require support for both CCM and DCM modes. Consider the 16-SOIC package constraints and the specified operating temperature range of -40°C to 125°C. Verify that the input voltage requirements fall within the 11V to 16.5V range. Evaluate the switching frequency capabilities between 66kHz and 84kHz against system performance needs.
Part Context
The FAN4800 series includes variants such as FAN4800ANY, FAN4800ASMY, and FAN4800IMX. These components are generally classified under PMIC - Power Management ICs, specifically for PFC applications. The FAN4800IM shares functional similarities with other members of the family but differs in packaging and potentially in specific operational parameters defined by its suffix.
Replacement Considerations
Check for official substitute part numbers from onsemi if this component is unavailable. Review datasheets for compatible alternatives within the same product family. Ensure any replacement maintains the required CCM/DCM functionality and package compatibility.
