TPS62873Z5WRXSR TI Step-Down Converter | 16-VQFN (2.55x3.55) | 2.7V-6V Input, 3A Output

Product Overview

The TPS62873Z5WRXSR is a high-efficiency, synchronous step-down (buck) converter from Texas Instruments, designed for space-constrained applications. It operates over a wide input voltage range of 2.7V to 6V and delivers up to 3A of continuous output current. The device is housed in a compact 16-pin VQFN package measuring 2.55mm x 3.55mm, making it ideal for portable and low-profile designs. With an integrated 25mΩ high-side and 15mΩ low-side MOSFET, the TPS62873Z5WRXSR achieves excellent efficiency and thermal performance.
