Introduction

AI Translation

TPS543320 is a high-efficiency 18V, 3A synchronous buck converter featuring internally compensated, fixed-frequency advanced current mode control. The device delivers high efficiency at switching frequencies up to 2.2MHz. Housed in a compact 2.5mm × 3mm HotRod VQFN package with high efficiency at elevated frequencies, it is an ideal choice for designs requiring a small solution size. The fixed-frequency controller operates from 500kHz to 2.2MHz and can be synchronized to an external clock via the SYNC pin. Additional features include a high-accuracy voltage reference, selectable soft-start time, monotonic startup into pre-biased outputs, selectable current limit, adjustable UVLO (via the EN pin), and a comprehensive suite of fault protections.
