R2A20114AFP#W5

Overview

The R2A20114AFP#W5 is a Power Factor Correction (PFC) integrated circuit manufactured by Renesas Electronics Corporation. It functions as a boost converter control IC designed for continuous conduction mode (CCM) interleaving PFC applications. The device operates within a switching frequency range of 70kHz to 86kHz. It is housed in a 40-LQFP package with dimensions of 7x7 mm. This component is specifically engineered to enhance power efficiency and reduce harmonic distortion in AC/DC conversion systems.

Feature Summary

• Implements continuous conduction mode (CCM) interleaving PFC technology for improved power factor correction.
• Functions as a dedicated boost converter control IC for high-efficiency power management.
• Designed to minimize total harmonic distortion (THD) in power supply applications.

Applications

• AC/DC power supplies requiring high power factor correction
• Industrial power conversion systems
• Consumer electronics power adapters

Procurement Notes

Verify the obsolete lifecycle status before procurement planning. Confirm compatibility with existing PCB footprints for the 40-LQFP (7x7) package. Ensure design reviews account for the specific 70kHz to 86kHz operating frequency range. Validate that alternative components meet identical interleaving CCM requirements if substitution is necessary due to availability constraints.

Selection Notes

Select this component for designs requiring interleaved CCM PFC control without external complex sensing circuits. It suits applications where a 7x7 mm LQFP package fits the thermal and spatial constraints. Consider its fixed frequency range when designing input/output filters. Evaluate system-level THD specifications against the IC's inherent performance capabilities for compliance.

Part Context

This part belongs to Renesas' portfolio of analog power devices focused on efficient energy conversion. It addresses the need for compact, high-performance PFC solutions in modern electronic equipment. The R2A20114 series represents specialized control logic for managing boost converter stages in power factor correction circuits.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete lifecycle status, direct replacements may require functional equivalence validation rather than pin-to-pin compatibility.
