General Description

The MAX20343 is an ultra-low quiescent current, noninverting buck-boost converter with 1A current capability at 3.5V intended for applications that require long run times while also demanding bursts of high current. The device employs a unique control algorithm which seamlessly transitions between buck, buck-boost, and boost modes, minimizing discontinuities and subharmonics in the output voltage ripple.

The low 1.9V input voltage for startup allows users to power the device from a variety of sources, and the near-zero minimum operating voltage gives the user the ability to extract as much as possible from their energy source.

The MAX20343 has also been designed to keep inductance and output capacitance requirements as low as possible for space-constrained applications.
