MAX765ESA+ Equivalent & Substitute Parts

Part Overview

The MAX765ESA+ 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 with a single negative output, delivering 120mA at adjustable or fixed voltage levels between -1V and -16V. The device operates across an input voltage range of 3V to 16V with a switching frequency of 300kHz and is housed in an 8-SOIC surface mount package. The MAX765ESA+ maintains Active product status and is ROHS3 compliant, making it suitable for modern electronic applications requiring negative rail generation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX765ESA+ is determined by strict alignment with the following critical parameters:

• Topology & Function: Buck-boost switching regulator with step-up/step-down capability
• Output Configuration: Negative voltage output
• Number of Outputs: Single output
• Voltage Range: Input 3V–16V; output -1V to -16V
• Current Capacity: 120mA output current
• Switching Frequency: 300kHz operation
• Package: 8-SOIC surface mount form factor
• Compliance: ROHS3 compliant, Active product status

Only components matching all these parameters across electrical specifications and physical packaging qualify as direct substitutes. The MAX765ESA+ itself represents the complete substitute list based on the provided input data.

Engineering Selection Recommendations

The MAX765ESA+ is the specified component for applications requiring negative voltage buck-boost regulation within the defined electrical and thermal parameters. Component selection should be based on:

• Product Status: Active status ensures ongoing manufacturer support and supply chain availability
• Compliance Certifications: ROHS3 compliance satisfies environmental and regulatory requirements for modern electronics manufacturing
• Moisture Sensitivity Level (MSL): Level 1 (Unlimited) indicates no moisture-related handling restrictions during assembly and storage
• Package Compatibility: The 8-SOIC form factor with 0.154" width (3.90mm) must match PCB layout and thermal management requirements

Selection of alternative components outside the specified parameters requires independent electrical and thermal validation.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX765ESA+?

A: A valid substitute must match all critical parameters: buck-boost topology, negative output configuration, single output, 3V–16V input range, -1V to -16V output range, 120mA current capacity, 300kHz switching frequency, 8-SOIC package, and ROHS3 compliance.

Q: Can the MAX765ESA+ be replaced with a different package type?

A: No. The 8-SOIC (0.154", 3.90mm Width) package is a fixed requirement. Different package types alter PCB footprint, thermal characteristics, and board layout compatibility.

Q: Is the operating temperature range -40°C ~ 85°C critical for substitution?

A: Yes. The operating temperature range defines the thermal envelope for the application. Substitutes must support the same or wider temperature range to ensure functional reliability across all operating conditions.

Q: What is the significance of the 300kHz switching frequency?

A: The switching frequency determines EMI characteristics, component sizing, and power efficiency. Substitutes must operate at 300kHz to maintain circuit performance and compliance with the original design specifications.

Q: Does MSL Level 1 affect component handling?

A: No. MSL Level 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Standard handling procedures apply without special moisture control requirements.

Q: Can a component with higher output current replace the MAX765ESA+?

A: Higher current capacity does not automatically qualify as a substitute. The component must match all specified parameters exactly. Oversizing current capacity may introduce unnecessary cost and board space inefficiency.
