TPS62321YZDR TI Step-Down Converter | 8-DSBGA | 3A, 3MHz

Product Overview

The TPS62321YZDR from Texas Instruments is a high-efficiency, synchronous step-down DC-DC converter optimized for low-power applications. It delivers up to 3A continuous output current from a 2.5V to 5.5V input supply. The device operates at a 3MHz fixed switching frequency, enabling the use of small external components. Housed in a compact 8-DSBGA package (1.5mm x 1.5mm), it is ideal for space-constrained designs.
