TPS51225BRUKR

Overview

The TPS51225BRUKR is a dual synchronous step-down controller from Texas Instruments, designed for high-efficiency power conversion. It operates with an input voltage range of 4.5 V to 5.5 V and supports switching frequencies between 300 kHz and 355 kHz. The device delivers up to 10 A output current per phase and features integrated 5-V and 3.3-V LDOs. Packaged in a WQFN-20 format, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual synchronous buck topology for independent multi-rail generation
• Integrated low-dropout regulators providing auxiliary power rails
• D-CAP control mode for stable operation across varying load conditions

Applications

• Server and storage backplane power distribution
• Industrial equipment main power regulation
• Telecommunications infrastructure power supplies

Procurement Notes

Verify the specific suffix 'BRUKR' against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the WQFN-20 package. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly integration.

Selection Notes

Select this component when designing systems requiring two isolated or non-isolated buck outputs from a single 5-V rail. It is suitable for applications needing integrated LDOs for logic or bias supplies. Consider thermal performance and layout requirements associated with the WQFN-20 package for optimal heat dissipation.
