IRU3012CW

Voltage Regulators - DC DC Switching Regulators Overview

The IRU3012CW is a synchronous step-down switching regulator IC manufactured by Infineon Technologies. It integrates high-side and low-side power MOSFETs into a single package to provide efficient voltage regulation for point-of-load applications. The device operates with an input voltage range supporting standard bus voltages and delivers adjustable output voltages via external feedback resistors. It utilizes a fixed-frequency current mode control architecture to ensure rapid transient response and loop stability. The component is housed in a 20-lead SOIC package, designed for surface-mount assembly on printed circuit boards.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix of the part number against official documentation, as variations may indicate different temperature ranges or packaging options. Confirm RoHS compliance status directly from the manufacturer datasheet, as historical data indicates potential non-compliance for certain variants. Ensure the procurement source provides valid traceability and authenticity guarantees given the component's discontinued status.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution for moderate current applications is required without the need for external power transistors. Consider the thermal performance of the 20-SOIC package relative to the expected load current and ambient conditions. Evaluate the fixed switching frequency against electromagnetic interference requirements and inductor size constraints. Verify that the input voltage range aligns with the system power rail specifications.

Voltage Regulators - DC DC Switching Regulators Part Context

The IRU3012 belongs to the IRU301x family of synchronous buck converters, which were previously distributed by International Rectifier before its acquisition by Infineon Technologies. This series was designed to offer a balance between performance and integration level for mid-range power applications. The CW variant specifically denotes the plastic SOIC package option within this product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status of the IRU3012CW, engineers should consult Infineon's current portfolio for modern replacements such as the TDA5xxx or IR38xx series, ensuring compatibility with existing board layouts and control loop parameters.
