The MAXM20343 and MAXM20344 are ultra-low quiescent current, non-inverting buck-boost, Himalaya modules with an integrated inductor. The MAXM20343 and MAXM20344 operate over a wide input range of 0.5V to 5.5V, support up to 2.5W output power and allow the use of small, low-cost input and output capacitors. The output voltage can be adjusted from 2.5V to 5.5V. The modules significantly reduce design complexity, manufacturing risks and offer a true plug-and-play power supply solution, reducing time-to-market.
The MAXM20343 and MAXM20344 employ 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. Both modules use an adaptive frequency mechanism to increase the 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. The MAXM20343 offers active discharge upon shutdown for fast decay of output voltage. The MAXM20344 does not offer active discharge upon shutdown but supports applications that have prebiased output voltage.
