MAX20049ATEF/VY+

Overview

The MAX20049ATEF/VY+ is a compact power management IC (PMIC) designed for remote camera power applications. It integrates four step-down converters and dual low-dropout regulators (LDOs). The buck converters operate at a switching frequency of 2.2MHz with a peak current capability of 500mA each. The device supports an input voltage range suitable for automotive environments, typically up to 36V. It features a 16-pin package optimized for small form factor designs.

Feature Summary

• Integrates four independent 500mA buck converters and dual LDOs in a single compact package
• Optimized for automotive camera modules with high switching frequency to minimize external component size
• Designed specifically for remote camera power supply requirements

Applications

• Automotive camera modules
• Remote camera power systems
• Point-of-load power distribution in vehicles

Procurement Notes

Verify the specific suffix 'ATEF' against the manufacturer's official datasheet to confirm pinout and electrical characteristics. Ensure compatibility with AEC-Q100 automotive grade requirements if used in vehicle systems. Cross-reference the package type and thermal specifications with your PCB layout design before finalizing procurement.

Selection Notes

Select this component when a highly integrated solution is required for powering multiple camera sensors from a single source. It is suitable for designs where board space is limited and multiple regulated rails are needed. Consider the 2.2MHz switching frequency for EMI management and component size trade-offs compared to lower frequency alternatives.

Part Context

This part belongs to the MAX20049 family of mini PMICs from Analog Devices/Maxim Integrated. These devices are engineered to simplify power architecture in automotive vision systems by combining multiple conversion stages into one footprint, reducing assembly complexity and improving reliability in harsh automotive environments.

Replacement Considerations

Check for other variants within the MAX20049 family such as MAX20049ATEG or MAX20049ATEK which may offer different output configurations or package options. Verify functional equivalence with any proposed substitutes to ensure compatibility with existing camera module interfaces.
