MAX16931ATLS/V+

DC DC Switching Controllers Overview

The MAX16931ATLS/V+ is a dual buck DC-DC controller with an integrated boost pre-regulator, designed for automotive applications. It operates within a supply voltage range of 3.5V to 42V and supports switching frequencies between 200kHz and 1MHz. The device features synchronous rectification and clock synchronization capabilities. It is housed in a 40-TQFN (6x6) package with exposed pad, rated for operation from -40°C to 125°C, and holds AEC-Q100 qualification.

DC DC Switching Controllers Feature Summary

• Integrates two synchronous buck converters with a dedicated boost pre-regulator stage
• Supports external clock synchronization for noise immunity and system timing alignment
• Includes comprehensive protection features such as thermal shutdown and overcurrent protection

DC DC Switching Controllers Applications

• Automotive infotainment systems requiring multiple regulated voltage rails
• Digital cockpit displays and instrument clusters
• ADAS sensor power management units

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'ATLS' against the manufacturer's current datasheet to confirm pinout and electrical specifications, as suffixes often denote temperature grade or packaging variations. Confirm AEC-Q100 status directly with Analog Devices documentation. Check for obsolescence notices or PCN alerts prior to final design approval.

DC DC Switching Controllers Selection Notes

Select this component when designing automotive power architectures that require a wide input voltage range up to 42V with high efficiency. The integrated boost pre-regulator simplifies designs where input voltage may drop below output requirements. Ensure the 40-TQFN thermal performance meets the application's heat dissipation needs.
