MAX765EPA Equivalent & Substitute Parts

Part Overview

The MAX765EPA is a buck-boost switching regulator IC from Analog Devices Inc./Maxim Integrated, designed to generate negative adjustable or fixed output voltages (-1V to -12V) from a 3V to 16V input supply. This device operates at 300kHz switching frequency and delivers up to 120mA output current in an 8-DIP through-hole package. The MAX765EPA is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX765EPA is determined by strict equivalence across the following critical parameters:

• Topology & Function: Buck-boost switching regulator with step-up/step-down capability
• Output Configuration: Negative voltage output
• Voltage Specifications: Input range 3V–16V; output range -1V to -16V
• Current Rating: 120mA output current minimum
• Switching Frequency: 300kHz operation
• Package: 8-DIP (0.300", 7.62mm) through-hole form factor
• Electrical Performance: Identical functional characteristics across all rated parameters

The MAX765EPA+ qualifies as a direct substitute based on complete parameter alignment with the main part, with the distinction that it maintains active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX765EPA+ is the direct equivalent substitute for the MAX765EPA. Both parts share identical electrical specifications, functional characteristics, and package form factor. The primary distinction is product lifecycle status: the MAX765EPA is obsolete, while the MAX765EPA+ maintains active production status.

For new designs and ongoing production, the MAX765EPA+ is the appropriate selection. It provides ROHS3 compliance, addressing modern regulatory requirements that the original MAX765EPA does not meet. Both parts maintain identical REACH and ECCN classifications, ensuring equivalent export and supply chain compliance.

The through-hole 8-DIP package format is consistent across both parts, enabling direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX765EPA+ directly replace MAX765EPA in existing designs?

A: Yes. The MAX765EPA+ is electrically and mechanically identical to the MAX765EPA. Pin configuration, package dimensions (8-DIP, 0.300" spacing), and all electrical parameters are equivalent. No circuit modifications are required.

Q: What is the key difference between MAX765EPA and MAX765EPA+?

A: The MAX765EPA+ is the active production variant with ROHS3 compliance certification. The MAX765EPA is classified as obsolete. Both parts deliver identical performance across all rated electrical and thermal parameters.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pinout and mechanical dimensions. PCB layouts are fully compatible.

Q: What output voltage range does this regulator support?

A: The MAX765EPA and MAX765EPA+ generate negative output voltages from -1V to -16V, with adjustable or fixed configuration options depending on external component selection.

Q: What input voltage range is supported?

A: Both parts accept input voltages from 3V to 16V, enabling operation across a wide range of supply sources.

Q: Is the MAX765EPA still available for purchase?

A: The MAX765EPA is classified as obsolete. The MAX765EPA+ is the active equivalent available through authorized distributors.
