R2A20118ASP#W5

Overview

The R2A20118ASP#W5 is a mixed-signal power factor correction (PFC) integrated circuit manufactured by Renesas Electronics. It operates in Critical Conduction Mode (CRM) and functions as an interleaved PFC control IC for boost converters. The device supports a supply voltage of 24V and features a 20-SOP package with surface mount installation. It operates within a temperature range of -40°C to 125°C.

Feature Summary

• Implements Critical Conduction Mode (CRM) operation for active power factor correction
• Designed as an interleaved control IC for seamless power management
• Controls boost converter topology to enhance power efficiency

Applications

• Active power factor correction circuits
• Boost converter control systems
• Power supply units requiring CRM operation

Procurement Notes

Verify the specific suffix #W5 against official Renesas documentation to confirm packaging details such as reel specifications or tape-and-reel dimensions. Ensure the operating temperature range of -40°C to 125°C aligns with your thermal design requirements. Confirm that the 20-SOP package dimensions match your PCB footprint constraints before finalizing procurement.

Selection Notes

Select this component when interleaved Critical Conduction Mode control is required for high-efficiency power factor correction. It is suitable for applications needing a dedicated PFC controller that manages boost converters with a 24V supply. Consider the 20-SOP package size and industrial temperature range (-40°C to 125°C) for compatibility with your system's physical and environmental constraints.

Part Context

This part belongs to the R2A20118 series, which is based on the R2A20117 architecture. It is specifically engineered to provide seamless power factor correction in mixed-signal environments. The device integrates control logic for interleaved operations, distinguishing it from single-phase CRM controllers.

Replacement Considerations

The R2A20117 is referenced as the base architecture for the R2A20118 series. Verify functional compatibility if substituting with earlier generation parts, noting that the R2A20118 includes additional features over the R2A20117.
