Texas Instruments Buck-Boost Switching Regulator, 1.8V to 5.5V In, 3.3V 800mA,
Texas Instruments 3.3V 800mA buck-boost switching regulator. 1.8V-5.5V input, 96% efficient, 2.4MHz, VSON-10 package.
The Texas Instruments Buck-Boost Switching Regulator is a highly efficient, fixed-output voltage regulator designed for precise power management in compact electronic designs. It features a buck-boost topology, allowing it to provide a stable 3.3V output from an input voltage that can vary between 1.8V and 5.5V. This makes it an ideal solution for battery-powered applications where the supply voltage may fall below the desired output level.
With a substantial output current capability of 800mA, this regulator can power a wide range of microcontrollers, sensors, and peripheral components. Its high typical switching frequency of 2.4MHz enables the use of smaller external inductors and capacitors, saving valuable board space in space-constrained designs. The component achieves an impressive typical efficiency of 96%, minimising power loss and extending battery life in portable devices.
Housed in a compact VSON-10 surface-mount package, it is suited for automated assembly processes. The regulator operates reliably across a broad temperature range from -40°C to +85°C, ensuring performance in industrial and automotive environments. Its fixed output voltage simplifies design by eliminating the need for external feedback resistors.
