TPS65573DSSR TI Power Management IC | 12-WSON (3x2) | 2.7V-5.5V Input, 3A Output

Product Overview

The TPS65573DSSR from Texas Instruments is a high-efficiency, synchronous step-down (buck) converter designed for space-constrained applications. It integrates a 3A continuous output current capability with a wide input voltage range of 2.7V to 5.5V, making it ideal for low-voltage power rails in portable and industrial systems. The device is housed in a compact 12-pin WSON package (3mm x 2mm) with a 0.5mm pitch, enabling minimal PCB footprint. With a switching frequency of 2.25MHz, it allows the use of small external inductors and capacitors, reducing overall solution size.
