MAX16920BATJ/V+T

Overview

The MAX16920BATJ/V+T is an automotive-grade power management integrated circuit featuring three synchronous step-down DC/DC converters and one low-dropout linear regulator. It operates within a wide input voltage range of 5.5V to 18V and supports switching frequencies up to 2.2MHz. The device provides four independent outputs, including specific configurations such as 5V at 150mA for the first channel. It is housed in a 32-pin TQFN package with an exposed pad and is qualified to AEC-Q100 standards for operation between -40°C and +125°C.

Feature Summary

• Integrates three high-efficiency synchronous buck converters and one LDO for comprehensive power distribution.
• Supports wide input voltage ranges suitable for automotive battery systems.
• Includes robust thermal management capabilities for high-temperature environments.
• Features programmable switching frequencies to optimize efficiency and component size.

Applications

• Automotive infotainment system power distribution
• Telematics control unit power supplies
• Body control module (BCM) voltage regulation
• ADAS sensor interface power management

Procurement Notes

Verify the exact suffix and tape-and-reel quantity against the manufacturer's current datasheet, as packaging specifications may vary by region or production lot. Confirm AEC-Q100 qualification status directly with Analog Devices, as automotive reliability certifications are subject to periodic review and potential updates in official documentation.

Selection Notes

Select this component when designing automotive electronics requiring multiple regulated rails from a single wide-voltage input source. Ensure the total output current requirements across all three buck converters and the LDO remain within the device's thermal limits. Verify that the required output voltages align with the supported adjustable ranges and that the 32-pin TQFN footprint fits the PCB layout constraints.

Part Context
