MAX20049DATEB/VY+

Overview

The MAX20049DATEB/VY+ is a compact power management IC designed for automotive applications, specifically remote camera systems. It integrates two synchronous step-down (buck) converters and two low-dropout (LDO) regulators on a single chip. The device operates with an input voltage range of 3.5V to 17V. The switching frequency for the buck converters is fixed at 2.2MHz. It supports output voltages including 2.8V/1.8V for the buck stages and 2.8V/1.2V for the LDO stages. The component is rated for an ambient temperature range of -40°C to +125°C and utilizes a SWTQFN-EP-16 package.

Feature Summary

• Integrates dual buck converters and dual LDOs in a single mini PMIC solution
• Optimized for space-constrained automotive camera power architectures
• Operates within extended industrial temperature ranges suitable for vehicle environments

Applications

• Remote camera power supply modules
• Automotive infotainment system power distribution
• Compact embedded vision systems

Procurement Notes

Verify the specific suffix DATEB against the official Analog Devices datasheet to confirm pinout and thermal pad configuration. Ensure the supplier provides valid traceability documentation for automotive-grade components. Confirm that the SWTQFN-EP-16 package matches your PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a small form factor is required for powering multiple rails in automotive cameras. It replaces discrete regulator solutions by combining buck and linear regulation. Consider the 2.2MHz switching frequency for EMI management and inductor size trade-offs. Verify that the combined current capabilities of the four outputs meet the specific load requirements of the target application.

Part Context

This part belongs to the MAX20049 family of mini PMICs developed by Maxim Integrated, now part of Analog Devices. These devices are engineered to reduce board space and simplify design-in processes for automotive visual systems. The family offers integrated protection features and high efficiency compared to discrete implementations.

Replacement Considerations

Check for MAX20049 variants with different suffixes such as DATEE or DATEJ if alternative packaging or minor electrical parameter variations are acceptable. Ensure any substitute maintains the same 16-pin SWTQFN-EP footprint and compatible output voltage configurations.
