MAXM20343AMP+

MAXM20343AMP+ is an ultra-low quiescent current, non-inverting buck-boost, Himalaya module with an integrated inductor. The module significantly reduces design complexity, manufacturing risks and offers a true plug-and-play power supply solution, reducing time-to-market. It employs a unique control algorithm that transitions between buck, buck boost, and boost modes of operation, minimizing discontinuities and sub-harmonics in the output voltage ripple. The module uses an adaptive frequency mechanism to increase efficiency at light loads. The low 1.9V startup input voltage allows users to power the modules from a variety of sources and the 0.5V minimum operating voltage offers the ability to extract as much energy as possible from the source. Typical applications include industrial sensors, low-power WAN, wearables and IoT.
