MAX1765EEE+ Equivalent & Substitute Parts

Part Overview

The MAX1765EEE+ is a dual-output power management IC combining a synchronous step-up (boost) converter and a linear low-dropout regulator. This PMIC operates at 1MHz switching frequency and is designed for applications requiring independent voltage regulation on two separate outputs. The device is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications across the -40°C to 85°C operating temperature range.

Substitute Part Grouping Explanation

Substitution for the MAX1765EEE+ is determined by strict equivalence across the following critical parameters:

• Dual-output topology: Step-up (boost) synchronous converter paired with linear LDO regulator
• Output count: Exactly 2 independent outputs
• Switching frequency: 1MHz operation
• Output voltage specifications: Output 1 range of 2.5V ~ 5.5V at 800mA; Output 2 at 2.85V/Adj at 500mA
• Supply voltage range: 0.7V ~ 5.5V input capability
• Package format: 16-QSOP surface mount configuration
• Operating temperature range: -40°C to 85°C
• Compliance certifications: RoHS3 compliance and MSL Level 1 rating

Only parts meeting all these specifications qualify as direct substitutes. The MAX1765EEE+ itself represents the complete equivalent specification set for this application requirement.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX1765EEE+? A: A valid substitute must provide identical dual-output topology (synchronous boost plus linear LDO), 1MHz switching frequency, matching output voltage and current specifications, 16-QSOP package format, and equivalent compliance certifications (RoHS3, MSL Level 1).

Q: Can the MAX1765EEE+ be replaced with a single-output regulator? A: No. The MAX1765EEE+ is specifically designed for dual independent outputs. Single-output alternatives do not meet the functional requirements of this component specification.

Q: Is the 16-QSOP package interchangeable with other surface mount packages? A: The 16-QSOP package (0.154" width, 3.90mm) is specific to this device footprint. PCB layout and routing must accommodate this exact package geometry. Alternative packages require board redesign.

Q: What is the significance of the 1MHz switching frequency? A: The 1MHz switching frequency determines EMI characteristics, inductor and capacitor sizing, and overall power conversion efficiency. Substitutes must operate at identical frequency to maintain circuit performance and compliance with EMI standards.

Q: Does the MAX1765EEE+ require external components? A: The specifications provided do not include external component requirements. Refer to the device datasheet for complete application circuit design guidance.

Q: Are there packaging options other than tube for the MAX1765EEE+? A: The provided specifications indicate tube packaging. Alternative packaging formats are not included in the available substitute data.
