The TPS543A26 is a high-efficiency 18V, 16A synchronous buck converter employing an internally compensated, fixed-frequency advanced current mode (ACM) control architecture, which while always operating under FCCM, generates output voltages from 0.5V to 7V. The device is capable of providing high efficiency while operating at a switching frequency up to 2.2MHz, making the device an excellent choice 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, two-wire remote sense, selectable soft-start times, monotonic start-up into prebiased outputs, selectable current limits, adjustable UVLO through the EN pin, and a full suite of fault protections.

The TPS543A26 is available in a small 2.5mm × 4.5mm HotRod™ WQFN-FCRLF package.
