MAX20049ATEA/VY+T

Overview

The MAX20049ATEA/VY+T is a flexible, compact quad power supply designed for automotive camera modules. It integrates two step-down (buck) regulators and two linear (LDO) regulators within a 16-pin SW-TQFN package. The device features 2.2MHz buck converters capable of delivering up to 500mA. Outputs include fixed voltages such as 3V, 3.1V, and 3.3V. It operates across an extended temperature range from -40°C to +125°C and holds AEC-Q100 qualification for automotive reliability.

Feature Summary

• Integrates dual 2.2MHz buck converters and dual LDOs in a single compact package
• Provides multiple fixed output voltage options including 3V, 3.1V, and 3.3V
• Delivers high current capacity with 500mA capability on buck outputs
• Qualified for automotive environments with extended operating temperature range

Applications

• Automotive camera module power supplies
• Remote camera power management systems
• Vehicle infotainment system power distribution
• ADAS sensor power regulation

Procurement Notes

Verify the specific suffix 'EA/VY+T' against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad specifications. Ensure the component meets AEC-Q100 grade requirements for your target automotive application. Confirm that the 16-SW-TQFN footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a multi-rail power solution is required for automotive vision systems. The integrated buck and LDO topology reduces board space compared to discrete solutions. Consider the 2.2MHz switching frequency for EMI management and passive component size optimization. Verify that the fixed output voltages align with the specific voltage requirements of the camera sensors and processing units.
