MAX25249BATPE/VY+

Overview

The MAX25249BATPE/VY+ is a high-efficiency, four-output mini PMIC designed for automotive camera applications. It integrates three DC-DC converters and one LDO within a 20-WETQFN package. The device operates from an input voltage range of 4.5V to 36V. Output 1 provides up to 1A via a synchronous step-down converter. Outputs 2 and 3 deliver up to 1.2A each with adjustable voltages from 0.8V to 3.9875V. Output 4 is a low-noise LDO rated at 1A. The unit features a fixed 2.2MHz switching frequency and complies with AEC-Q100 and ASIL-B standards.

Feature Summary

• Integrates three synchronous buck converters and one high-PSRR LDO in a compact form factor
• Includes overvoltage and undervoltage monitoring on all outputs with error communication via reset
• Features programmable spread-spectrum frequency modulation to minimize radiated electromagnetic emissions
• Supports factory-settable output voltages and flexible sequencing through dedicated enable pins

Applications

• Surround-view cameras
• Rear-view cameras
• High-megapixel camera systems
• Image sensor power rails

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type and availability status. Confirm that the component meets required automotive qualification standards for the target deployment environment. Ensure compatibility with existing system voltage profiles before integration. Check for any recent manufacturing updates or lifecycle changes directly from the manufacturer.

Selection Notes

Select this component when designing power architectures for automotive imaging systems requiring integrated regulation. The device suits applications needing multiple regulated rails from a single high-voltage source. Consider its ASIL-B compliance for safety-critical vehicle functions. Evaluate thermal performance requirements based on the intended load currents and ambient operating conditions.
