MAX16993AGJG/VY+

Voltage Regulators - DC DC Switching Regulators Overview

The MAX16993AGJG/VY+ is a triple-output synchronous step-down DC-DC controller from the MAX16993 series, manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 3.5 V to 36 V and delivers up to 3 A per output channel. The device integrates three independent buck converters switching at a fixed frequency of 2.1 MHz. Output voltages are adjustable or fixed at 3.3 V and 5 V, with a minimum programmable setting of 0.8 V. It features a low quiescent current of 30 µA and meets AEC-Q100 automotive qualification standards. The component is housed in a 32-pin QFND-EP package and supports operation temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (VY+) against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad specifications. Confirm that the AEC-Q100 qualification status aligns with your project's automotive grade requirements. Check for any recent obsolescence notices or lifecycle changes directly from Analog Devices documentation before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring three isolated or coupled low-voltage rails from a single higher-voltage source. The 2.1 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure the PCB layout accommodates the exposed pad thermal dissipation requirements of the QFND-EP package. Verify that the input voltage never exceeds the 36 V maximum rating under all transient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX16993 family of triple-output controllers designed for space-constrained applications. It shares core architecture with variants like MAX16993AGJA and MAX16993AGJD, differing primarily in packaging or minor electrical tolerances. The series targets automotive infotainment and industrial sectors where board real estate is limited but multiple voltage domains are necessary.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Cross-reference with MAX16993AGJA/VY+ or MAX16993AGJD/VY+ for potential functional equivalents within the same product line. Verify package dimensions and thermal characteristics match the existing footprint. Consult the manufacturer's substitution guide to ensure no critical parameter deviations exist between the original and candidate parts.
