Overview
The R2A20124AFP#W5 is a synchronous phase-shift switching controller manufactured by Renesas Electronics Corporation. It operates in current-mode control with a maximum switching frequency of 200kHz and supports an output current of 0.2A. The device is housed in a PQFP40 package. Official documentation identifies it as a component for power factor correction (PFC) applications, utilizing a full-bridge phase-shift switching circuit architecture.
Feature Summary
- Supports synchronous phase-shift switching topology
- Utilizes current-mode control strategy
- Designed for power factor correction circuits
Applications
- Power factor correction systems
- Synchronous rectification controllers
- Phase-shift full-bridge converters
Procurement Notes
Verify the specific suffix #W5 against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the PQFP40 form factor. Cross-reference electrical parameters with the latest datasheet revision to avoid discrepancies from older variants like the R2A20121 series.
Selection Notes
Select this component for designs requiring synchronous phase-shift control with current-mode regulation. Confirm that the 200kHz maximum switching frequency aligns with thermal and efficiency targets. Verify that the 0.2A current capability meets load requirements. Compare against legacy models such as the R2A20121SP if upgrading existing architectures.
Part Context
This part belongs to Renesas' power management integrated circuit portfolio, specifically targeting high-efficiency AC/DC conversion stages. It complements other PFC and DC-DC controllers in industrial and consumer power supply designs. The PQFP40 package offers a balance of thermal performance and pin count for complex control logic integration.
Replacement Considerations
The R2A20121SP is a related phase-shift controller but lacks explicit confirmation of functional equivalence for the AFP variant. No officially confirmed direct substitute part numbers are available in public documentation. Evaluate pinout and parameter compatibility carefully before substitution.
