company blog about Texas Instruments TPS543B25TRASR A High Efficiency 18V, 25A Synchronous Buck Converter

Shenzhen Mingjiada Electronics Co., Ltd [Supply] Texas Instruments TPS543B25TRASR A high efficiency 18V, 25A synchronous step-down converter with internally compensated fixed frequency advanced current mode (ACM) control architecture.

Product Description - TPS543B25TRASR

The device offers high efficiency and operates at switching frequencies up to 2.2MHz, making it suitable for designs that require a small solution size. The fixed frequency controller can operate from 500kHz to 2.2MHz and can be synchronised to an external clock via the SYNC pin. Other features include a high-precision voltage reference, two-wire remote sensing, selectable soft-start time, monotonic start-up to a pre-biased output, selectable current limiting, adjustable UVLO via the EN pin, and full fault protection.

The TPS543B25TRASR is available in a small 2.5mm × 4.5mm HotRod™ WQFN-FCRLF package.
