TPS546D24RVFR Description

Short technical summary and product information.

The TPS546D24RVFR from Texas Instruments is a high-performance 40A stackable synchronous buck converter, part of the SWIFT family. It is designed for efficient power management with a wide input voltage range of 2.95V to 16V and an output voltage adjustable from 0.25V to 5.5V via PMBus or pin strapping.

This converter features integrated MOSFETs with low on-resistance (4.5mΩ/0.9mΩ) and supports stackable configurations for up to 160A total output current with current sharing. It utilizes Average Current Mode Control with selectable internal compensation and offers extensive PMBus command set with telemetry for monitoring and control.

The TPS546D24RVFR operates within an industrial temperature range of -40°C to 125°C and is housed in a compact LQFN-CLIP (RVF) package measuring 7mm x 5mm. Its features include adaptive voltage scaling, adjustable current limit, differential remote sense, and power good indication, making it suitable for demanding power applications.
