MAX25249BATPD/VY+T

Overview

The MAX25249BATPD/VY+T is a four-output mini PMIC for camera applications, integrating three DC-DC converters and one high-PSRR LDO. It 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 for imager power. The device features 2.2MHz fixed-frequency PWM, ±1.5% output accuracy, and ASIL-B compliance.

Feature Summary

• Integrates three synchronous buck converters and one high-PSRR LDO in a compact package
• Provides overvoltage and undervoltage fault monitoring with error communication through the RESET pin
• Features programmable spread-spectrum frequency modulation to minimize radiated electromagnetic emissions
• Compliant with ASIL-B safety ratings and AEC-Q100 automotive qualification standards

Applications

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

Procurement Notes

Verify the specific suffix PD against official Analog Devices documentation to confirm pinout and thermal pad configuration differences compared to other variants like PC or PB. Ensure the component meets ASIL-B requirements for your target application. Confirm availability status as supply conditions may vary by region and distributor.

Selection Notes

Select this part when designing automotive camera systems requiring integrated power management with high noise immunity. The 2.2MHz switching frequency allows for smaller external components. Verify that the required output currents and voltage ranges align with the sensor and serializer specifications before finalizing the design.
