MAX1586CETM+

Overview

The MAX1586CETM+ is a high-efficiency, low-quiescent current Power Management IC (PMIC) designed for portable applications. It integrates seven output channels within a single package to minimize board space. The device operates from an input voltage range of 2.6 V to 5.5 V and features a fixed switching frequency of 1 MHz. Key outputs include fixed voltages of 1.8 V and 2.5 V, alongside adjustable regulators. The unit supports an output current of 500 mA per channel and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates multiple power rails into a compact solution to reduce overall system footprint.
• Optimized for battery-powered devices through ultra-low quiescent current consumption.
• Includes dynamic core voltage scaling capabilities to enhance efficiency during varying load conditions.

Applications

• Personal Digital Assistants (PDAs)
• Smartphones
• Portable Media Players

Procurement Notes

Verify the specific suffix 'C' against the target design requirements, as it denotes a particular bin or revision within the MAX1586 family. Confirm that the TQFN-EP-48 package matches the PCB thermal pad layout. Ensure the component meets RoHS compliance standards required by the final assembly destination. Cross-reference the datasheet revision date to guarantee compatibility with existing firmware control logic.

Selection Notes

Select this component when a multi-rail power solution is required for handheld electronics. It is suitable for designs needing simultaneous supply generation for processors, memory, and peripherals. Consider the 48-pin TQFN package for its thermal performance and small outline dimensions. Evaluate the 1 MHz switching frequency against electromagnetic interference constraints in dense layouts.

Part Context

This part belongs to the MAX1586 series of PMICs developed by Maxim Integrated, now part of Analog Devices. These components are engineered specifically for mobile communication devices requiring efficient power management. The series typically consolidates several linear and switching regulators into one chip to simplify circuit design and improve reliability in space-constrained environments.

Replacement Considerations

Check for MAX1586AETM-T or MAX1586BETM+ variants if different output configurations or packaging formats are acceptable. Verify pin-to-pin compatibility before substitution. Review datasheet differences regarding specific output voltages and thermal characteristics to ensure functional equivalence.
