R2A20113SP#W0

Overview

The R2A20113SP#W0 is a synchronous step-down DC/DC converter from Renesas Electronics Corporation. It operates with an input voltage range of 4.5V to 28V and provides a single adjustable output channel. The device supports a maximum output current of 3A and features a fixed switching frequency of 600kHz. It utilizes an I²C interface for configuration and monitoring, including programmable soft-start and over-current protection settings.

Feature Summary

• Integrated synchronous rectification for high efficiency
• I²C configurable digital control interface
• Wide input voltage compatibility
• Built-in thermal and current protection

Applications

• Industrial equipment power distribution
• Telecommunications infrastructure
• Point-of-load regulation for embedded systems

Procurement Notes

Verify the specific suffix W0 against the manufacturer's official datasheet to confirm package type and temperature rating. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design. Cross-reference with authorized distributors to confirm current availability and authenticity.

Selection Notes

Select this component when a compact, digitally controlled buck converter is needed for mid-range current applications. It is suitable for designs requiring precise voltage regulation via I²C rather than analog feedback alone. Consider the 600kHz frequency for balancing component size and efficiency.

Part Context

This part belongs to Renesas' family of synchronous buck converters designed for industrial and communication markets. It complements other power management solutions by offering digital flexibility in a small footprint, targeting applications where system monitoring and programmability are critical requirements.

Replacement Considerations

Consult the official Renesas replacement guide or datasheet revision history for confirmed cross-references. Do not assume functional equivalence with generic buck converters without verifying pinout and control interface compatibility.
