MAX20049ATEK/VY+

Overview

The MAX20049ATEK/VY+ is a compact power management IC designed for remote camera applications. It integrates four independent power supplies: two 2.2MHz, 500mA buck converters and two low-dropout regulators (LDOs). The device operates with an input voltage range of 2.7V to 5.5V. It features integrated inductors to minimize solution size and includes programmable soft-start, enable controls, and thermal shutdown protection. The component is housed in a 16-pin, 3mm x 3mm wafer-level chip-scale package (WLCSP) optimized for space-constrained automotive environments.

Feature Summary

• Integrates dual high-frequency buck converters and dual LDOs within a single compact footprint
• Utilizes integrated inductors to significantly reduce overall board area requirements
• Includes comprehensive protection mechanisms such as thermal shutdown and overcurrent limiting

Applications

• Automotive camera modules
• Remote vision systems
• Compact vehicle electronics

Procurement Notes

Verify the specific suffix (ATEK/VY+) against official Analog Devices documentation to confirm pinout and functional specifications. Ensure compatibility with automotive grade requirements if used in vehicle systems. Confirm lead times and availability through authorized distributors, as standard lead times may vary. Cross-reference datasheet revisions to ensure design integrity.

Selection Notes

Select this component when space constraints are critical due to its integrated inductor design. Suitable for applications requiring multiple regulated rails from a single source. Verify that the required output currents do not exceed the 500mA limit per buck converter. Consider the operating temperature range and packaging type for integration into the target PCB layout.

Part Context

This part belongs to the MAX20049 family of mini PMICs developed by Maxim Integrated, now part of Analog Devices. These devices are specifically engineered to replace discrete power solutions in automotive imaging systems. The family offers flexibility in configuring multiple power rails while maintaining a small form factor suitable for modern vehicle architectures.

Replacement Considerations

Check for direct substitutes like the MAX20049ATEG/VY+ or MAX20049ATEA/VY+ which share similar functionalities but may differ in packaging or specific electrical characteristics. Always verify pin-to-pin compatibility and parameter alignment before substitution.
