FAN7530MX

Overview

The FAN7530MX is a critical conduction mode (CRM) power factor correction controller manufactured by onsemi. It operates within an input voltage range of 9.5 V to 22 V, with a nominal rating of 14 V. The device utilizes pulse width modulation and voltage-mode control techniques for active PFC applications in boost topologies. It is housed in an 8-pin SOIC package and supports surface mount installation. The component functions across a temperature range of -40°C to +125°C.

Feature Summary

• Implements critical conduction mode operation for boost power factor correction circuits
• Integrates voltage-mode control with pulse width modulation technology
• Designed for active PFC applications requiring CRM functionality

Applications

• Boost Power Factor Correction (PFC) circuits
• Active PFC controller implementations
• Critical Conduction Mode (CRM) power supply designs

Procurement Notes

Verify the specific manufacturer designation carefully, as historical records indicate Fairchild Semiconductor origin before corporate integration into onsemi. Confirm the RoHS compliance status through official documentation, as supplier listings may vary regarding environmental certification details. Ensure the part number suffix matches the required tape and reel packaging configuration for automated assembly processes.

Selection Notes

Select this component for designs requiring a dedicated CRM PFC controller rather than boundary or continuous conduction modes. Evaluate the 8-SOIC package constraints against thermal dissipation requirements and PCB layout space. Consider the operating voltage window compatibility with the system's supply rails and ensure the control loop stability aligns with the voltage-mode architecture specifications.

Part Context

This component belongs to the FAN7530 series of power management integrated circuits. It is categorized under PMIC - Power Management ICs, specifically within the Power Factor Controllers subcategory. The device represents a legacy product line originally developed by Fairchild Semiconductor, now maintained under the onsemi portfolio for standard AC-DC conversion applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other onsemi CRM controllers such as the NCP16xx series if pin-to-pin compatibility is required, though functional differences must be verified via respective datasheets.
