MAX765EPA+ Equivalent & Substitute Parts

Part Overview

The MAX765EPA+ is a buck-boost switching regulator IC from Analog Devices Inc./Maxim Integrated designed for negative output voltage regulation. This component functions as a step-up/step-down converter capable of generating a fixed negative output of -1V or -12V with a maximum output current of 120mA. The device operates across an input voltage range of 3V to 16V and maintains active product status with full RoHS3 compliance. Alternative equivalent parts may be required due to inventory constraints, supply chain considerations, or specific application requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX765EPA+ is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish the substitution criteria:

Electrical Parameters (Must Match Exactly):

• Function: Step-Up/Step-Down (Buck-Boost topology)
• Output Configuration: Negative
• Output Type: Adjustable (Fixed)
• Number of Outputs: 1
• Voltage - Input Range: 3V to 16V
• Voltage - Output: -1V (-12V) fixed, maximum -16V
• Current - Output: 120mA
• Frequency - Switching: 300kHz
• Synchronous Rectifier: No

Mechanical Parameters (Must Match Exactly):

• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Supplier Device Package: 8-PDIP

Compliance & Status (Must Match):

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Operating Temperature Range: -40°C ~ 85°C (TA)

Only components meeting all specified criteria across electrical, mechanical, and compliance parameters qualify as direct substitutes.

Engineering Selection Recommendations

The MAX765EPA+ maintains active product status with full RoHS3 compliance and REACH unaffected designation, confirming its suitability for current design implementations. The component carries Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during assembly and storage. ECCN classification as EAR99 establishes standard export compliance without additional regulatory constraints.

Selection of equivalent parts must prioritize exact parameter matching across all electrical specifications, particularly the negative output configuration, fixed voltage levels, and 120mA output current rating. The 8-DIP through-hole package format is critical for PCB layout compatibility and must not be substituted with alternative package types. Compliance certifications, including RoHS3 status and operating temperature range, must remain consistent with the original specification to ensure regulatory and functional equivalence.

Frequently Asked Questions (FAQ)

Q: What defines a direct substitute for the MAX765EPA+? A: A direct substitute must match all electrical parameters (buck-boost topology, negative output, -1V/-12V fixed voltage, 120mA output, 300kHz switching frequency), mechanical specifications (8-DIP through-hole package), and compliance certifications (RoHS3, Active status) without deviation.

Q: Can the MAX765EPA+ be replaced with a different package type? A: No. The 8-DIP (0.300", 7.62mm) through-hole package is a fixed requirement. Alternative package formats are not compatible substitutes due to PCB layout and assembly process constraints.

Q: Are there compatibility considerations for negative output voltage applications? A: The negative output configuration is integral to the MAX765EPA+ design. Substitutes must maintain identical negative polarity and fixed voltage levels (-1V or -12V) to ensure circuit compatibility and prevent damage to connected components.

Q: What is the significance of the 300kHz switching frequency? A: The 300kHz switching frequency is a core design parameter affecting EMI characteristics, component selection for filtering networks, and overall circuit performance. Substitutes must maintain this exact frequency specification.

Q: Does the RoHS3 compliance status affect substitute selection? A: Yes. RoHS3 compliance is mandatory for regulatory equivalence. All substitute parts must carry identical RoHS3 certification to meet environmental and legal requirements.

Q: What is the operating temperature range requirement? A: The MAX765EPA+ operates across -40°C to 85°C (TA). Substitute components must support this identical temperature range to ensure reliable operation across all specified environmental conditions.

Q: Is the Moisture Sensitivity Level 1 rating important for substitutes? A: Yes. MSL 1 (Unlimited) indicates no moisture-related handling restrictions. Substitutes must maintain this MSL rating to avoid additional storage and assembly process requirements.
