The Texas Instruments TPS546D24ARVFR is a high-performance 40A synchronous step-down (buck) converter from the SWIFT™ family. It features PMBus communication for control and monitoring, along with pin-strapping options. The device supports a wide input voltage range of 2.95V to 16V and can deliver an output current of up to 40A. The output voltage is adjustable from 0.25V to 5.5V.
Designed for efficiency and power density, the TPS546D24ARVFR integrates low-resistance MOSFETs (4.5mΩ/0.9mΩ) and utilizes average current mode control with selectable internal compensation. It supports phase interleaving for improved thermal performance and reduced input/output ripple. The converter can be stacked 2x, 3x, or 4x for current sharing up to 160A.
This converter operates over an industrial temperature range of -40°C to 150°C (TA). It is housed in a 40-pin LQFN-CLIP package measuring 7mm x 5mm, suitable for surface mounting. Key features include adaptive voltage scaling, adjustable current limit, differential remote sense, power good indication, and adjustable soft-start.
Applications for the TPS546D24ARVFR include high-density power systems, servers, telecom equipment, and industrial power supplies requiring high current and precise voltage regulation.
