MAX20049ATEA/VY+

Overview

The MAX20049ATEA/VY+ is a compact power management IC designed for remote camera applications. It integrates four synchronous buck converters, each capable of delivering up to 500mA. The device operates with an input voltage range of 2.7V to 36V and supports switching frequencies of 2.2MHz or 4.4MHz. It features programmable output voltages and includes integrated soft-start functionality to limit inrush current. The component is housed in a small 16-pin SW-TQFN package measuring 3mm x 3mm, suitable for space-constrained designs.

Procurement Notes

Verify the specific suffix 'ATEA' against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure compatibility with required input voltage ranges and thermal dissipation requirements for the target application environment before finalizing procurement.

Selection Notes

Select this component when multiple low-current rails are required within a minimal footprint. Evaluate the trade-off between switching frequency and external component size, as higher frequencies allow for smaller inductors but may impact efficiency. Confirm that the 500mA per channel rating meets the peak load demands of all connected subsystems.

Part Context

This part belongs to the MAX20049 family of mini PMICs optimized for automotive camera applications. It consolidates multiple discrete regulators into a single solution, reducing board area and simplifying design complexity compared to using individual buck converters for each power rail.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic replacements may not match the specific integration level or package dimensions.
