TPS53124PW

DC DC Switching Controllers Overview

The TPS53124PW is a dual synchronous step-down controller from Texas Instruments, designed for low voltage power rails in embedded computing. It operates with an input voltage range of 3V to 28V and provides two regulated outputs. The device supports output currents up to 10A per channel and features a switching frequency range of 240kHz to 420kHz. It functions within an operating temperature range of -40°C to +85°C and is housed in a 24-pin VQFN package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-16 or similar package variant as listed in official TI documentation, ensuring compatibility with your PCB footprint. Confirm RoHS compliance status and check for any recent lifecycle notifications or PCNs that may affect long-term availability or material composition changes.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated or coupled buck channels are required for embedded applications. Ensure the design accommodates the 240kHz to 420kHz switching frequency range and verify that the thermal performance meets requirements for the intended ambient conditions and load profiles.

DC DC Switching Controllers Part Context

This part belongs to the TPS531xx series of DCAP2 controllers, which are optimized for high-efficiency power conversion in compact form factors. It complements other single-channel variants by providing integrated dual-phase control capabilities without requiring external synchronization components for basic operation.

DC DC Switching Controllers Replacement Considerations

Check for direct pin-to-pin replacements within the TPS531xx family, such as the TPS53127, if higher current capacity or different packaging options are needed. Verify electrical parameter compatibility before substitution.
