A monolithic synchronous buck-boost DC/DC converter provides a wide input and output voltage range of 2.7V to 40V, delivering up to 2A of output current. Utilizing a low noise switching algorithm, it achieves up to 95% efficiency with a programmable switching frequency from 100kHz to 2MHz, ensuring a seamless transition between buck and boost modes. This robust device operates across a -40°C to 125°C temperature range and includes features such as internal soft-start, output disconnect in shutdown, and short-circuit protection. Power-sensitive applications benefit from a quiescent current of 30µA in Burst Mode and just 3µA in shutdown.
