TPS51275CRUKR

Overview

The TPS51275CRUKR is a mixed-signal power management IC from Texas Instruments, integrating two synchronous buck converters and two low-dropout linear regulators. It operates within an input voltage range of 5V to 24V and supports switching frequencies of 300kHz and 355kHz. The device features four outputs, including controller-driven synchronous buck stages and fixed 3.3V/100mA LDOs. It is housed in a 20-WQFN (3x3) package with exposed pad, designed for surface mount installation across an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates dual synchronous buck controllers and dual LDO regulators in a single compact package
• Supports wide input voltage range suitable for various system power rails
• Utilizes D-CAP™ control architecture for stable operation

Applications

• Industrial equipment power distribution
• Telecommunications infrastructure systems
• Embedded computing platforms requiring multiple voltage rails

Procurement Notes

Verify the specific suffix 'C' against the official datasheet to confirm the exact electrical characteristics and pinout configuration intended for your design. Ensure compatibility with the 20-WQFN thermal requirements during layout. Confirm RoHS compliance status through current manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when a combined solution for high-current DC-DC conversion and low-noise analog supply generation is required. The integration reduces board space compared to discrete implementations. Consider the 300kHz/355kHz frequency options for optimizing external inductor size versus transient response needs.

Part Context

This part belongs to the TPS51275 family of mixed-signal PMICs. The 'C' suffix typically denotes specific performance grades or material revisions within the series. It serves as a consolidated power solution alternative to separate buck and LDO components, streamlining the bill of materials for complex multi-rail systems.

Replacement Considerations

Consult the official TPS51275 datasheet for direct cross-reference information. Verify if the TPS51275BRUKR or TPS51275RUKR variants meet the specific thermal or electrical requirements of the application.
