TPS61097A-33DBVR | TI 3.3V Boost Converter | 0.7V Startup | Low Power & High Efficiency

Product Overview

     The TPS61097A-33DBVR from Texas Instruments is an ultra-low-voltage boost converter that starts up from input voltages as low as 0.7 V and continues operation down to 0.5 V. It provides a fixed 3.3 V output with up to 95% efficiency and an ultra-low quiescent current of approximately 1 µA, making it ideal for battery-powered, coin-cell, or energy-harvesting applications.

     The device integrates a synchronous rectifier MOSFET and pulse-skipping control to maintain efficiency at light loads. With its compact SOT-23-5 (DBV) package and wide output capability (1.8 V–5.5 V), the TPS61097A-33 is ideal for powering MCUs, sensors, and RF modules in low-power systems.
