R2A20104FP#W5

Overview

The R2A20104FP#W5 is a Power Factor Correction (PFC) controller manufactured by Renesas Electronics Corporation. It is designed for continuous conduction mode (CCM) applications and operates with a switching frequency of 86 kHz. The device is housed in a 40-lead LQFP package. Typical supply current (Icc) is 5 mA. It supports CT sensing, frequency modulation, and synchronization input/output functions.

Feature Summary

• Supports continuous conduction mode (CCM) PFC applications
• Integrates current transformer (CT) sensing capability
• Provides frequency modulation and synchronization I/O functionality

Applications

• Power factor correction circuits
• AC/DC power supply systems

Procurement Notes

Verify the specific suffix #W5 to confirm the tape and reel packaging configuration. Confirm that the 40-lead LQFP package dimensions match your PCB footprint requirements. Ensure compatibility with CCM control strategies and external components required for the 86 kHz operation frequency.

Selection Notes

Select this component when a dedicated PFC controller for CCM topology is required. Consider the 86 kHz operating frequency for EMI filtering design. Verify that the system requires CT sensing rather than resistive or Hall-effect current sensing. Check if synchronization input/output is needed for multi-phase or parallel converter designs.

Part Context

This part belongs to Renesas' portfolio of PMIC solutions focused on power management. It complements other power stage drivers and controllers in scalable power supply architectures. The device addresses efficiency and compliance requirements in modern electronic power conversion systems.

Replacement Considerations

Check for direct pin-compatible alternatives from Renesas or other manufacturers offering CCM PFC controllers in 40-LQFP packages. Verify functional equivalence regarding CT sensing support and synchronization capabilities before substitution.
