Analog Devices MAX20361

Small, Single-/Multi-Cell Solar Harvester with MPPT and Harvest Counter

Overview

TopologyBoost Converter
Input voltage0.22-2.5 V
Output 13.8 V / 0.01 A
IC revision3

Description

The MAX20361 is a fully integrated solution for harvesting energy from single-/multi-cell solar sources. The device includes an ultra-low quiescent current (360nA) boost converter that is capable of starting from input voltages as low as 225mV (typ). In order to maximize the power extracted from the source, the MAX20361 implements a proprietary maximum power point tracking (MPPT) technique that allows efficient harvesting from 15μW to over 300mW of available input power.
