TPS51275BRUKT

Overview

The TPS51275BRUKT is a dual synchronous buck switching voltage regulator from the Texas Instruments TPS51275B series. It operates within an input voltage range of 5V to 24V and features two independent output channels. The device integrates two synchronous buck converters and two low-dropout (LDO) regulators, providing four total outputs in a single package. It utilizes D-CAP control topology with a fixed switching frequency between 300 kHz and 355 kHz. The component is housed in a 20-pin WQFN (3x3 mm) package with an exposed thermal pad, designed for surface-mount installation.

Feature Summary

• Integrates two synchronous buck converters and two LDO regulators for combined power management
• Utilizes D-CAP control topology for stable operation without external compensation networks
• Supports wide input voltage range suitable for various bus architectures
• Includes built-in protection mechanisms such as thermal shutdown

Applications

• Industrial equipment power distribution
• Telecommunications infrastructure systems
• Enterprise computing platforms

Procurement Notes

Verify the specific suffix 'BRUKT' to confirm the cut-tape packaging variant and ensure compatibility with automated pick-and-place assembly processes. Confirm that the MSL rating and reflow soldering profile requirements align with your manufacturing capabilities. Cross-reference the datasheet revision to ensure all electrical characteristics match your design specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact solution requiring both high-current buck regulation and precise LDO outputs is necessary. The integrated nature reduces board space compared to discrete solutions. Ensure the thermal design accommodates the power dissipation in the 20-WQFN package. Verify that the required output voltages fall within the adjustable ranges specified in the official documentation.

Part Context

This part belongs to the TPS51275 family of mixed-signal PMICs. Variants like the TPS51275RUKR and TPS51275CRUKR share similar pinouts and core functionalities but may differ in temperature ratings or internal parameter tolerances. The BRUKT designation specifically indicates the tape and reel or cut-tape packaging format available through distributors.

Replacement Considerations

Direct substitutes include TPS51275RUKT and TPS51275CRUKT. These parts maintain functional compatibility within the same family. Verify temperature grade and packaging differences before substitution.
