Overview
The FAN4803CP1 is a critical conduction mode (CRM) power factor correction controller manufactured by onsemi. It operates with an average current control mode and features a fixed switching frequency of 67kHz. The device is designed for high-efficiency PFC applications, supporting a supply voltage range of 10V to 15V. It has a startup current of 200 µA and functions within an operating temperature range of 0°C to 70°C. The component is housed in an 8-DIP package.
Feature Summary
- Implements critical conduction mode operation for enhanced efficiency
- Utilizes average current control methodology
- Fixed 67kHz switching frequency architecture
Applications
- Power factor correction circuits
- AC-DC power supplies
- Industrial power management systems
Procurement Notes
Verify the specific package type required, as the FAN4803 series includes both SOIC and DIP variants. Confirm availability status, as some distributors list this part as discontinued or obsolete. Ensure compatibility with existing PCB footprints for 8-DIP packages if replacing older designs. Check for RoHS compliance documentation from the manufacturer.
Selection Notes
Select this component for applications requiring CRM PFC control with a fixed frequency. Consider the 8-DIP package constraint for through-hole assembly requirements. Evaluate the 0°C to 70°C operating temperature range against environmental conditions. Compare the 67kHz frequency against EMI constraints and magnetic component sizing needs.
Part Context
The FAN4803 belongs to onsemi's family of power factor correction controllers. It is distinct from the FAN4803CS1X, which utilizes an 8-SOIC surface-mount package. Both variants share similar electrical characteristics but differ in physical packaging and mounting technology. The CP1 suffix specifically denotes the dual in-line package configuration.
Replacement Considerations
FAN4803CS1X is a pin-compatible alternative with an 8-SOIC package. Verify that the target application supports surface-mount technology if substituting the CS1X variant. Ensure thermal performance meets requirements for the different package styles.
