The TPS613223ADBVT is a fixed-output step-up (boost) converter from Texas Instruments, delivering a regulated 2V rail from inputs as low as 0.9V. The integrated 1.2A switch supports loads up to several hundred milliamps depending on input voltage and efficiency — a practical fit for powering a 2V sensor or logic rail from a single alkaline or Li-primary cell.
Within the TPS61322x family, the TPS613223ADBVT is the fixed 2V output variant. Other fixed-voltage versions (e.g., TPS613221ADBVT with a different output) share the same SOT-23-5 footprint and pinout, but the output voltage differs — confirm the BOM voltage before substituting.
