TPS543820 Synchronous SWIFT™ Step-Down Converter

Texas Instruments TPS543820 Synchronous SWIFT™ Step-Down Converter is a high-efficiency 18V, 8A synchronous buck converter employing an internally-compensated, fixed-frequency Advanced Current Mode control. It is capable of providing high efficiency while running at a switching frequency of up to 2.2MHz. The Texas Instruments TPS543820 is in a small 2.5mm × 3mm HotRod™ VQFN package, which, when coupled with high efficiency at high frequency, makes it optimal for designs requiring a small solution size. The fixed frequency controller can operate from 500kHz to 2.2MHz and can be synchronized to an external clock using the SYNC pin. Additional features include a high accuracy voltage reference, 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.
