TPS543B25 & TPS543B25T Step-Down Converters

Texas Instruments TPS543B25 and TPS543B25T Synchronous SWIFT™ Step-Down Converters are high-efficiency 18V, 25A buck converters employing an internally compensated and fixed-frequency Advanced Current Mode (ACM) control architecture. These converters operate under FCCM and generate output voltages from 0.5V to 7V. The fixed frequency controller can operate from 500kHz to 2.2MHz and be synchronized to an external clock using the SYNC pin. Additional features include a high-accuracy voltage reference, two-wire remote sense, selectable soft-start times, selectable current limits, and a full suite of fault protections. The TPS543B25 and TPS543B25T converters are used in fiber networks, test and measurement, and healthcare applications.
