MAX20029ATIA/V+

MAX20029ATIA/V+ is an automotive low-voltage step down DC-DC converter. This power-management IC (PMIC) integrates four low-voltage, high-efficiency, step-down DC-DC converters. The PMIC operates from 3.0V to 5.5V, making it ideal for automotive point-of load and post-regulation applications. It features fixed-frequency PWM-mode operation with a switching frequency of 2.2MHz. High-frequency operation allows for an all-ceramic capacitor design and small-size external components. The low-resistance onchip switches ensure high efficiency at heavy loads while minimizing critical inductances, making the layout a much simpler task with respect to discrete solutions. Internal current sensing and loop compensation reduce board space and system cost. It provides individual enable inputs and power good/ reset outputs, as well as factory-programmable PG times. It offers a SYNC input to synchronize to an external clock. Typical applications are automotive, industrial.
