MAX1765EEE Equivalent & Substitute Parts

Part Overview

The MAX1765EEE is a dual-output power management IC (PMIC) combining a synchronous step-up (boost) converter and a linear (LDO) regulator in a 16-QSOP surface mount package. This device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The MAX1765EEE operates from a 0.7V to 5.5V supply and delivers independent regulated outputs suitable for multi-rail power distribution applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX1765EEE is determined by strict equivalence across the following electrical and mechanical parameters:

• Dual-output topology: synchronous boost converter and linear regulator
• Output voltage and current specifications matching Output 1 (2.5V ~ 5.5V, 800mA) and Output 2 (2.85V/Adj, 500mA)
• Switching frequency of 1MHz
• Supply voltage range of 0.7V ~ 5.5V
• Operating temperature range of -40°C ~ 85°C
• 16-QSOP package footprint and pinout compatibility
• Surface mount configuration

The MAX1765EEE+ is identified as a direct substitute based on identical electrical specifications, topology, output ratings, frequency, supply range, temperature range, and package configuration. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX1765EEE+ is the direct functional equivalent of the MAX1765EEE. Both devices share identical electrical specifications, topology, output ratings, frequency, supply voltage range, temperature range, and package configuration.

The MAX1765EEE+ is recommended for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The MAX1765EEE, classified as obsolete, is suitable only for legacy system maintenance where existing inventory is available and RoHS compliance is not a requirement.

Selection between these parts should be based on product availability, supply chain continuity, and regulatory compliance requirements of the target application.
