MAX1587AETL+

Overview

The MAX1587AETL+ is a specialized power management IC (PMIC) designed for high-efficiency voltage regulation in low-voltage, high-current applications. It integrates three step-down DC-DC converters and three low-dropout regulators (LDOs). The device supports an input voltage range of 2.6 V to 5.5 V. Each step-down converter provides an output current capability of 0.5 A. The LDO outputs are regulated at fixed voltages including 1.8 V and 2.5 V, with one adjustable output. The component is housed in a TQFN-40 package.

Feature Summary

• Integrates six regulated power rails combining three switching converters and three LDOs
• Optimized for high efficiency in low-power handheld and embedded processing systems
• Features minimal quiescent current consumption for extended battery life

Applications

• Low-power handheld devices requiring efficient voltage regulation
• Embedded processing systems and edge computing modules
• Internet of Things (IoT) applications

Procurement Notes

Verify the exact ordering suffix and RoHS compliance status before procurement. Confirm that the TQFN-40 package matches your PCB footprint requirements. Ensure the input voltage range of 2.6 V to 5.5 V aligns with your system's power supply architecture. Check for availability as this component may be subject to limited supply conditions or end-of-life status depending on the distributor.

Selection Notes

Select this PMIC when a single solution is needed to provide multiple distinct voltage rails from a single input source. It is suitable for designs where space constraints favor integrated solutions over discrete components. Consider the thermal performance of the TQFN-40 package under maximum load conditions. Verify that the combined current requirements of the three buck converters and three LDOs do not exceed the device's total thermal dissipation capabilities.

Part Context

This component belongs to the Maxim Integrated line of specialized power management ICs. It is part of a family of devices designed to simplify power distribution in portable electronics. The MAX1587 series typically targets applications requiring compact footprints and high integration levels. Analog Devices Inc. acquired Maxim Integrated, maintaining the product lineage under the new corporate structure.
