MAX20021ATIA/V+ Description

Short technical summary and product information.

The MAX20021ATIA/V+ from Analog Devices is a power management IC integrating four low-voltage, high-efficiency, step-down DC-DC converters. Each of the four outputs is programmable between 1.0V to 4.0V and can deliver up to 1.0A of current. These PMICs operate from a 3.0V to 5.5V supply voltage, making them suitable for automotive point-of-load and post-regulation applications.

 

The converters feature fixed-frequency, PWM-mode operation with a switching frequency of 3.2MHz. This high-frequency operation allows for an all-ceramic capacitor design and small-size external components. The device includes internal current sensing and loop compensation to reduce board space and system cost. Protection features include input overvoltage protection, input undervoltage monitoring, cycle-by-cycle current limiting, and overtemperature shutdown.

 

The MAX20021ATIA/V+ is available in a 28-pin TQFN package with an exposed pad. It is specified for operation over the -40°C to +125°C automotive temperature range. The device offers individual enable inputs and power good/reset outputs to simplify sequencing.
