Overview

The TPS543A26 is a high-efficiency 18-V, 16-A 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 0.5 V to 7 V. The device is capable of providing high efficiency while operating at a switching frequency up to 2.2 MHz, making it optimal for designs requiring a small solution size. The fixed frequency controller can operate from 500 kHz to 2.2 MHz 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 startup 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 2.5-mm×4.5-mm HotRod WQFN-FCRLF package.
