MAX1586AETM+T

Overview

The MAX1586AETM+T is a high-efficiency, low-quiescent current power management IC designed for portable applications. It integrates seven output regulators within a compact 48-pin TQFN package. The device features a buck converter with an input voltage range of 2.6 V to 5.5 V and an adjustable output from 0.7 V to 5.5 V at up to 1.2 A. It includes six LDOs providing fixed outputs of 1.8 V and 2.5 V, plus one adjustable LDO. Operating at a switching frequency of 1 MHz, it supports temperatures from -40°C to +85°C.

Feature Summary

• Integrates multiple regulator types including buck and LDOs in a single chip
• Optimized for dynamic core voltage requirements in mobile processors
• Supports wide input voltage ranges suitable for battery-powered systems

Applications

• Personal Digital Assistants (PDAs)
• Smartphones
• Portable electronic devices requiring multi-rail power supplies

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm that the component is manufactured by Analog Devices or Maxim Integrated as specified. Ensure the order matches the exact part number MAX1586AETM+T to guarantee correct pinout and electrical characteristics. Check for RoHS compliance documentation if required for your assembly process.

Selection Notes

Select this component when designing systems requiring a single-chip solution for processor core and I/O power rails. It is suitable for space-constrained designs due to its small footprint. Consider the 1.2 A buck output capability for main logic power and the LDOs for sensitive analog circuits. Evaluate thermal performance given the dense integration in the 48-TQFN package.
