TPS62812MRWYRNEP TI Step-Down Converter | 9-VQFN-HR(3x2) | 2.7V-6V Input, 1A Output

Product Overview

The TPS62812MRWYRNEP from Texas Instruments is a high-efficiency, synchronous step-down (buck) converter capable of delivering up to 1A of continuous output current. It operates over a wide input voltage range of 2.7V to 6V, making it ideal for low-power applications powered by single-cell Li-ion batteries or 3.3V/5V rails. The device is housed in a compact 9-pin VQFN-HR package (3mm x 2mm) with a 0.5mm pitch, enabling space-constrained designs. With a typical quiescent current of 12µA and a switching frequency of 2.4MHz, it offers excellent efficiency across the load range.
