TPS546A24ARVFR Description

Short technical summary and product information.

The TPS546A24ARVFR from Texas Instruments is a high-performance, non-isolated DC/DC buck converter designed for demanding applications. It delivers up to 10A of output current and operates with an input voltage range from 2.95V to 18V.

 

This device features integrated 5.5-mΩ/1.8-mΩ MOSFETs and utilizes average current mode control with selectable internal compensation for optimal performance and stability. It supports stackable configurations (2x, 3x, 4x) for current sharing up to 40A on a single output, simplifying system design.

 

The TPS546A24ARVFR includes an extensive PMBus command set for configuration and telemetry, monitoring output voltage, output current, and internal die temperature. It also offers differential remote sensing for precise voltage regulation and supports features like AVS, margining, and prebiased startup.

 

Packaged in a compact 7mm x 5mm, 40-pin QFN package, this buck converter is suitable for surface mount applications. Its operating temperature range is -40°C to +150°C (TJ), making it robust for various environments. Applications include data center switches, rack servers, active antenna systems, and automated test equipment.
