Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5038AEAI25 is determined by strict equivalence across the following critical parameters:

• Output topology: Buck (step-down) configuration
• Output type: Transistor driver
• Output configuration: Positive
• Number of outputs and phases: 2 outputs, 2 phases
• Supply voltage range: 4.75V ~ 28V
• Switching frequency options: 250kHz, 500kHz
• Synchronous rectification capability: Required
• Package type: 28-SSOP form factor
• Operating temperature range: -40°C ~ 85°C
• Surface mount compatibility

The MAX5041EAI+ meets all these criteria and is manufactured by the same supplier, ensuring functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX5041EAI+ is the direct substitute for the obsolete MAX5038AEAI25. Both devices share identical electrical specifications across all critical parameters: supply voltage range, switching frequency options, output configuration, phase count, and thermal operating range. Both are ROHS3 compliant and carry MSL Level 1 rating, meeting equivalent environmental and regulatory requirements.

The MAX5041EAI+ is currently in active production status, ensuring long-term availability and supply chain continuity. The addition of Phase Control as a supplementary control feature in the MAX5041EAI+ does not affect backward compatibility and provides enhanced functionality for applications requiring phase management.

Frequently Asked Questions (FAQ)

Q: Can the MAX5041EAI+ directly replace the MAX5038AEAI25 in existing designs?

A: Yes. Both devices are housed in the 28-SSOP package with identical pinout and electrical specifications. No PCB layout modifications are required.

Q: What is the primary reason for substitution?

A: The MAX5038AEAI25 is obsolete. The MAX5041EAI+ is the active equivalent manufactured by Analog Devices Inc./Maxim Integrated.

Q: Are there differences in control features between these parts?

A: The MAX5041EAI+ includes Phase Control as an additional control feature beyond the Enable function present in the MAX5038AEAI25. This enhancement does not affect compatibility with existing designs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both devices are ROHS3 compliant with MSL Level 1 rating and operate across the identical temperature range of -40°C to 85°C.

Q: Is the 28-SSOP package identical for both parts?

A: Yes. Both parts use the 28-SSOP package with 0.209" width (5.30mm), ensuring mechanical and electrical compatibility on the same PCB footprint.
