Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX1971EEE+ is determined by strict alignment with the following critical parameters:

• Input voltage range: 2.6V to 5.5V minimum
• Output current capability: 750mA minimum
• Output configuration: Positive adjustable (programmable)
• Number of outputs: 2 outputs required
• Package type: 16-SSOP (0.154", 3.90mm Width)
• Switching frequency: 700kHz
• Synchronous rectifier: Present
• Operating temperature range: -40°C to 85°C minimum
• Product status: Active
• RoHS compliance: ROHS3 Compliant

Only components matching all specified parameters qualify as direct substitutes. The MAX1971EEE+ itself represents the primary reference specification for this application.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the MAX1971EEE+?

A: Direct substitution requires matching all critical specifications: dual positive adjustable outputs, 750mA current capability, 2.6V to 5.5V input range, 700kHz switching frequency, synchronous rectifier topology, 16-SSOP package, and Active product status with ROHS3 compliance.

Q: Can the MAX1971EEE+ be used in applications requiring single output?

A: The MAX1971EEE+ is specified with 2 outputs. Applications requiring single output configuration should evaluate alternative devices with single-output topology.

Q: Is the 16-SSOP package interchangeable with other SSOP variants?

A: The 16-SSOP (0.154", 3.90mm Width) package is specific to this device. Substitution requires identical package dimensions and pin configuration. Other SSOP variants with different widths or pin counts are not mechanically or electrically compatible.

Q: What is the significance of the 700kHz switching frequency?

A: The 700kHz switching frequency determines the size and type of external passive components (inductors and capacitors) required for the application circuit. Substitutes must maintain this frequency to ensure compatibility with existing board designs and component selections.

Q: Does the synchronous rectifier feature affect substitution criteria?

A: Yes. The presence of an integrated synchronous rectifier is a functional requirement for this device class. Substitutes must include this feature to maintain efficiency and thermal performance characteristics.

Q: What does ROHS3 compliance indicate?

A: ROHS3 compliance certifies that the device meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. This is a regulatory requirement for many markets and applications.
