TPS543A22 Synchronous SWIFT™ Step-Down Converter

Texas Instruments TPS543A22 Synchronous SWIFT™ Step-Down Converter is a high-efficiency 18V, 12A synchronous buck converter employing an internally compensated, fixed-frequency advanced current mode (ACM) control architecture. The device always operates under FCCM and generates output voltages from 0.5V to 7V. The device can provide high efficiency while working at a switching frequency of up to 2.2MHz, making it optimal for designs requiring a small solution size. 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, monotonic start-up into pre-biased outputs, selectable current limits, adjustable UVLO through the EN pin, and a full suite of fault protections. The Texas Instruments TPS543A22 is available in a small 2.5mm × 4.5mm HotRod™ WQFN-FCRLF package.
