The MAX20029/MAX20029B/MAX20029C/MAX20029D power-management ICs (PMICs) integrate four low-voltage, high-efficiency, step-down DC-DC converters. Each of the four outputs is factory or resistor programmable between 1V to 4.0V (MAX20029/MAX20029B) or 0.7V to 3.8V (MAX20029C/MAX20029D). The MAX20029/ MAX20029C has two 0.5A/1A/1.5A channels and two 0.5A/1.5A channels, while the MAX20029B/MAX20029D has two 0.5A/1.5A channels and by combining channels 1 and 2, a single 2A/3A channel. The PMICs operate from 3.0V to 5.5V, making them ideal for automotive point-ofload and post-regulation applications.
