TPS53124PWR

DC DC Switching Controllers Overview

The TPS53124PWR is a dual synchronous step-down switching controller manufactured by Texas Instruments. It operates within an input voltage range of 4.5 V to 24 V and supports output voltages from 760 mV to 5.5 V. The device features two independent output channels, each capable of delivering up to 15 A. It utilizes D-CAP+ control topology with a fixed switching frequency of 350 kHz and a maximum duty cycle of 89%. The component is housed in a 28-pin TSSOP package and functions reliably across an operating temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Dual-channel architecture for independent power rail generation
• D-CAP+ control topology for stable transient response
• Integrated synchronous rectification for high efficiency
• Wide input voltage compatibility for diverse system requirements

DC DC Switching Controllers Applications

• Server and data center point-of-load regulation
• Industrial equipment power distribution
• Telecommunications infrastructure power supplies
• High-performance computing systems

DC DC Switching Controllers Procurement Notes

Verify the specific package marking and date code against the official Texas Instruments datasheet to ensure authenticity. Confirm that the ordering suffix matches the required tape-and-reel quantity. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Ensure storage conditions comply with moisture sensitivity level requirements prior to assembly.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated outputs are required from a single controller. The 15 A per channel rating suits high-current applications. Verify that the PCB layout supports the thermal requirements of the TSSOP-28 package. Ensure the external switch components match the controller's drive capabilities and voltage ratings.

DC DC Switching Controllers Part Context

This part belongs to the TPS531xx series of multi-phase controllers designed for high-efficiency power conversion. It complements other variants like the TPS53124RGET which uses a VQFN package. The series targets applications requiring compact footprints and high current density in server and industrial environments.

DC DC Switching Controllers Replacement Considerations

The TPS53124RGET serves as a pin-compatible alternative with a different package type. Direct substitution requires verifying footprint compatibility and thermal performance differences between TSSOP-28 and VQFN-24 configurations.
