IRU3137CSTR

DC DC Switching Controllers Overview

The IRU3137CSTR is a positive output step-down (buck) DC-DC switching controller manufactured by Infineon Technologies. It operates within a supply voltage range of 4.25V to 25V and supports a fixed switching frequency of 200kHz. The device is designed for single-output applications and is housed in an 8-SOIC package with a width of 3.90mm. This controller integrates the necessary circuitry to regulate voltage efficiently in power management systems.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'STR' indicates tape and reel packaging when ordering. Confirm the 8-SOIC package dimensions match your PCB footprint requirements. Ensure the 4.25V minimum supply voltage aligns with your system's input rails. Check for RoHS compliance status if required by your manufacturing standards. Validate that the 200kHz frequency fits your EMI constraints.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a simple buck regulator solution with a wide input voltage range. The fixed 200kHz frequency simplifies external component selection compared to adjustable frequency controllers. Consider the 8-SOIC package size for space-constrained designs. Ensure the load current requirements are met by the external MOSFETs, as this is a controller rather than a complete converter IC.

DC DC Switching Controllers Part Context

This part belongs to Infineon's portfolio of DC-DC switching controllers. It serves as a core component in power management integrated circuits (PMIC) for converting higher input voltages to lower stable output levels. The device complements other power solutions by providing reliable regulation for various electronic loads.

DC DC Switching Controllers Replacement Considerations

Consult official Infineon documentation for direct pin-to-pin replacements or functional equivalents. Verify compatibility regarding switching frequency and input voltage ranges before substituting.
