MAX20049DATEA/VY+

Overview

The MAX20049DATEA/VY+ is a fully integrated synchronous buck converter and linear regulator IC designed for automotive camera applications. It accepts an input voltage range of 5V to 17V and provides four independent regulated outputs: two LDOs at 1.8V, one LDO at 3.3V, and one programmable buck converter outputting 1.2V. The device operates within a temperature range of -40°C to +125°C and utilizes a 16-SW-TQFN package with exposed pad.

Feature Summary

• Integrates dual step-down converters and low-dropout regulators into a single chip
• Provides dedicated power rails for automotive camera sensors and processing units
• Supports wide input voltage ranges suitable for automotive electrical systems

Applications

• Automotive digital still cameras
• Remote camera power solutions
• ADAS sensor power management

Procurement Notes

Verify the specific suffix 'DATEA' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the 16-SW-TQFN package dimensions align with your PCB footprint. Confirm RoHS compliance status as per the latest official documentation before finalizing procurement.

Selection Notes

Select this component when a compact solution is required to power multiple camera subsystems from a single 5V-17V source. It is appropriate for designs needing isolated 1.8V and 3.3V rails alongside a lower voltage buck output. Consider thermal performance in the small QFN package during high-load conditions.

Part Context

This part belongs to Maxim Integrated's mini PMIC family tailored for automotive imaging. It consolidates functions that would otherwise require discrete components, reducing board space and complexity. The device supports AEC-Q100 qualification standards for automotive reliability.

Replacement Considerations

Check for direct substitutes within the MAX20049 series or compatible PMICs from Analog Devices/Maxim that offer similar output configurations and package types.
