MAX8663ETL+

Power Management - Specialized Overview

The MAX8663ETL+ is a specialized power management IC designed for single-cell lithium-ion battery-operated devices. It integrates two high-efficiency 1MHz buck regulators within a compact 40-pin TQFN-EP package measuring 5mm x 5mm x 0.8mm. The main regulator supports output currents up to 1200mA with voltages ranging from 0.98V to VIN, while the core regulator provides stable power for internal circuitry. Operating across a supply voltage range of 4.1V to 8V and an extended temperature range of -40°C to +85°C, this component ensures reliable performance in portable applications requiring efficient energy utilization.

Power Management - Specialized Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to restricted availability status. Confirm RoHS compliance documentation matches current manufacturing standards. Ensure ordering suffixes align with specific package and temperature grade requirements. Cross-reference datasheet revisions against design specifications prior to procurement. Validate supply chain integrity to prevent counterfeit components.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring dual isolated power rails from a single lithium cell. Evaluate thermal dissipation capabilities given the 2.963W power dissipation rating. Consider the 1.5mA quiescent current impact on overall battery life. Assess PCB layout constraints imposed by the 40-pin TQFN footprint. Verify input voltage stability within the 4.1V to 8V operational window.

Power Management - Specialized Part Context

Part of the MAX8662/MAX8663 family of power management solutions targeting portable electronics. Shares architectural similarities with the MAX8662 but offers distinct pinout configurations. Designed to replace discrete regulator solutions in space-constrained mobile applications. Manufactured under Maxim Integrated's professional PMIC portfolio standards.

Power Management - Specialized Replacement Considerations

MAX8662ETM+ serves as a functional alternative within the same product family. Verify pin compatibility and regulatory output specifications before substitution. Check package dimensions and thermal characteristics for direct replacement feasibility.
