MAX20343NEWE: Ultra-Low Quiescent Current, Low Noise, 3.5W Buck/Boost Regulator

Model: MAX20343NEWE

Package: WLP-16

Type: Ultra Low Quiescent Current, In-Phase Boost/Buck Converter

The MAX20343NEWE is an ultra-low quiescent current, in-phase boost/buck converter with 1A @ 3.5V current drive capability for applications requiring long runtimes and high burst currents. The devices feature a proprietary control algorithm that smoothly switches between buck, boost/buck, and step-up modes to minimise output voltage ripple discontinuities and sub-harmonics.

The MAX20343NEWE is supported with a highly configurable I2C serial interface, or a fixed-setting version with single-pin support. The devices operate over the -40°C to +85°C temperature range and are available in a 16-ball, 1.77mm x 2.01mm, 0.4mm pitch WLP package and a 12-pin, 2.50mm x 2.50mm, 0.5mm pitch FC2QFN package.
