Description
The 7Semi DC‑DC Buck‑Boost Converter (TPS631000) delivers a regulated 3.3 V output across a wide input range from 1.6 V to 5.5 V. It’s tailored for systems where the supply voltage can fluctuate above and below the target output voltage, such as battery-powered devices. The converter automatically switches between buck, boost, and buck-boost operation, providing seamless and efficient regulation.
