MAX8668ETEV+T

Overview

The MAX8668ETEV+T is a power management integrated circuit from Analog Devices/Maxim Integrated, housed in a TQFN-16 package. It integrates two synchronous step-down DC-DC converters and two low-dropout (LDO) regulators within a single device. The switching regulators operate at a fixed frequency of 1.5 MHz and provide individual enables for each channel. Each buck converter delivers an output current of 1.2 A with adjustable output voltages ranging from 600 mV to 3.3 V. The dual LDOs offer additional regulated outputs. The component supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates two independent synchronous buck converters and two LDO regulators
• Features individual enable controls for each power channel
• Utilizes a fixed 1.5 MHz switching frequency for compact design

Applications

• Portable electronic devices requiring multiple voltage rails
• Battery-operated systems needing efficient power conversion
• Embedded applications with space-constrained PCB layouts

Procurement Notes

Verify the specific suffix EV against official documentation to confirm pinout and thermal characteristics. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the selected package matches the target footprint requirements. Cross-reference the manufacturer's latest datasheet for any revisions that might affect compatibility.

Selection Notes

Select this component when a compact solution is required for generating multiple supply voltages from a single input source. The integration of buck converters and LDOs reduces the total bill of materials and board area. Consider the 1.5 MHz frequency for balancing efficiency and passive component size. Verify that the combined load currents do not exceed the specified limits for each regulator type.

Part Context

This part belongs to the MAX8668 family of power management ICs designed for portable applications. It consolidates power conversion functions typically requiring separate components into a single small outline package. The series is characterized by high efficiency and low quiescent current, suitable for extending battery life in mobile devices.

Replacement Considerations

Check for direct pin-to-pin replacements within the same product family. Verify functional equivalence regarding output currents and voltage ranges. Ensure thermal performance and package dimensions are compatible with the existing design constraints.
