TPS51275CRUKT

Overview

The TPS51275CRUKT is a Texas Instruments PMIC featuring two synchronous buck converters and two LDOs. It operates with switching frequencies of 300 kHz and 355 kHz within an input voltage range of 5 V to 24 V. The device supports output voltages including 3.3 V and 5 V, housed in a 20-WQFN (3x3) package. It functions between -40°C and +85°C.

Feature Summary

• Integrates dual synchronous step-down controllers and dual low-dropout regulators for combined power management.
• Utilizes D-CAP™ control architecture for stable operation across varying load conditions.

Applications

• Portable electronic devices requiring multi-rail power distribution
• Industrial equipment needing compact DC/DC regulation
• Embedded systems utilizing mixed linear and switching topologies

Procurement Notes

Verify the specific suffix 'R' versus 'T' against official documentation, as these denote distinct packaging formats such as reel or cut tape. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering to ensure compatibility with assembly processes.

Selection Notes

Select this component when a single IC solution is required to manage both high-efficiency switching rails and precise linear outputs. Ensure the 5 V to 24 V input range aligns with system supply constraints and that the 20-WQFN footprint fits the PCB layout.

Part Context

This part belongs to the TPS51275 family, which combines switching and linear regulation technologies. It serves as a consolidated power management solution, reducing component count compared to discrete designs while maintaining flexibility for diverse voltage requirements in space-constrained applications.

Replacement Considerations

Consult official substitution lists for variants like TPS51275RUKR or TPS51275CRUKR. Verify pin compatibility and electrical specifications before replacing to ensure functional equivalence without circuit redesign.
