MAX8742EAI

Power Supply Controllers, Monitors Overview

The MAX8742EAI is a multi-output power-supply controller designed for applications requiring multiple regulated voltage rails. It integrates current-mode control architecture with high-impedance shutdown capability to minimize quiescent current during standby modes. The device supports dual switching outputs operating at a maximum frequency of 550kHz, enabling the use of compact passive components. It features integrated gate drivers capable of sourcing and sinking sufficient current to drive external power MOSFETs efficiently.

Power Supply Controllers, Monitors Feature Summary

• Integrates dual current-mode PWM controllers for independent output regulation
• Provides high-impedance shutdown state to reduce system power consumption
• Includes integrated gate drivers for direct MOSFET control without external buffers

Power Supply Controllers, Monitors Applications

• Telecommunications infrastructure power systems
• Industrial equipment requiring multiple voltage rails
• Computing systems with complex power management needs

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix (e.g., EAI vs EAI+) against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the component meets RoHS requirements if mandated by your assembly process. Cross-reference the ordering part number with Analog Devices documentation to avoid confusion with similar family members that may have different thermal or electrical characteristics.

Power Supply Controllers, Monitors Selection Notes

Select this component when designing systems that require two synchronized or asynchronous buck converters from a single controller IC. It is suitable for designs where board space is limited due to its integrated driver topology. Consider the 550kHz switching frequency limit when selecting inductors and capacitors to balance efficiency and size. Verify input voltage ranges match the target application's supply rails.

Power Supply Controllers, Monitors Part Context

This component belongs to the Maxim Integrated portfolio, now part of Analog Devices Inc. It is classified under PMIC - Power Supply Controllers. The device utilizes a 28-pin SSOP package. It is distinct from LED display drivers like the MAX6952 series, serving specifically as a switching regulator controller rather than a display interface chip.
