The TPS61252DSGR is a highly efficient, synchronous buck-boost converter integrated circuit (IC) designed for low-power applications. It can step up or step down input voltages, making it suitable for a wide range of battery-powered devices.
One of the key features of the TPS61252DSGR is its wide input voltage range capability, which can accommodate input voltages between 0.3V to 5.5V. This allows it to work with various power sources, including single-cell and multi-cell batteries, supercapacitors, and energy harvesting modules. The converter can deliver a stable output voltage with high efficiency even when the input voltage is lower or higher than the desired output voltage.
With a high switching frequency of up to 3.5 MHz, the TPS61252DSGR provides fast response times and allows the use of small external components, thus minimizing the overall footprint of the design. Moreover, this IC offers a wide range of output voltage options, adjustable via external resistors, making it highly flexible for different application requirements.
To ensure power optimization, the TPS61252DSGR incorporates advanced power-saving features such as pulse skipping mode and optional automatic transition between step-up and step-down modes. These mechanisms help maximize efficiency and extend battery life by reducing power consumption during light-load conditions
