MAX16993AGJG/VY+T

Voltage Regulators - DC DC Switching Regulators Overview

The MAX16993AGJG/VY+T is a triple-output synchronous step-down switching regulator controller designed for automotive applications. It integrates three independent buck converters, each operating at a fixed 2.1 MHz switching frequency to minimize external component size. The device supports an input voltage range from 3.5 V to 36 V and delivers up to 3 A per channel. Outputs are configurable for fixed 3.3 V or 5 V levels, or adjustable down to 0.8 V. It features AEC-Q100 qualification, operates between -40°C and +125°C, and includes shutdown functionality with low quiescent current of 30 µA.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'VY+' indicates lead-free and RoHS compliance status before procurement. Confirm the 'T' suffix denotes tape-and-reel packaging rather than tube. Ensure the specific grade matches your environmental requirements. Cross-reference the full part number against official Analog Devices documentation to confirm availability and revision status. Validate that the QFN-EP package footprint aligns with your PCB layout constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing multi-rail automotive power systems requiring high efficiency and small footprint. The fixed 2.1 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Choose this part if your application requires three isolated outputs from a single controller IC. Consider the thermal performance of the exposed pad package for high-current scenarios. Verify input voltage stability to ensure compatibility with the 36 V maximum rating.
