MAX16993ATJI/V+

The Analog Devices MAX16993ATJI/V+ is a multichannel, DC-DC converter PMIC designed for automotive applications. It integrates three supplies, including one high-voltage step-down controller and two low-voltage step-down converters cascaded from the first. This device operates from a 3.5V to 36V supply voltage and can handle load-dump transients up to 42V.

The MAX16993ATJI/V+ offers a switching frequency of 2.1MHz, with pin-selectable options for lower frequencies. The low-voltage converters can supply output currents up to 3A. Key features include a low quiescent current of 30µA under no-load conditions, overtemperature shutdown, overcurrent limiting, and individual RESET outputs for voltage monitoring.

This PMIC is available in a 32-pin TQFN or side-wettable QFND-EP package, making it suitable for space-constrained designs. It is specified for operation over an automotive temperature range of -40°C to +125°C. The device also includes a spread-spectrum enable input for improved electromagnetic interference (EMI) performance and a SYNC input for external clock synchronization.

Applications for the MAX16993ATJI/V+ include automotive and industrial systems requiring efficient power management. Its robust design and integrated features make it a reliable choice for demanding environments.
