MAX1652EEE+ Equivalent & Substitute Parts

Part Overview

The MAX1652EEE+ is a buck regulator positive output step-down DC-DC controller IC manufactured by Analog Devices Inc./Maxim Integrated. This 16-QSOP surface mount device functions as a transistor driver for step-down topology applications with dual output capability. The part is currently obsolete, making identification of active equivalent alternatives essential for ongoing design support and procurement continuity. Substitute parts must maintain electrical and mechanical compatibility while offering active product status for long-term availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX1652EEE+ is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Topology: Buck (Step-Down)
• Output Type: Transistor Driver
• Voltage Supply Range: 4.5V ~ 30V
• Switching Frequency: 150kHz, 300kHz
• Maximum Duty Cycle: 98%
• Synchronous Rectifier: Yes
• Clock Sync: Yes
• Control Features: Enable, Soft Start
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Package / Case: 16-SSOP (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameter (Allowed Difference):

• Number of Outputs: The MAX1652EEE+ features 2 outputs. Substitutes with 1 output (MAX1653EEE+, MAX1655EEE+) or 2 outputs (MAX1654EEE+) are acceptable based on application requirements.

All three substitute parts (MAX1653EEE+, MAX1654EEE+, MAX1655EEE+) maintain active product status and full compliance with the critical parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

For Dual-Output Applications: Select MAX1654EEE+ as the primary substitute for MAX1652EEE+. Both devices support 2 outputs and maintain identical electrical specifications, topology, and control features. MAX1654EEE+ is active and ROHS3 compliant, ensuring long-term procurement availability.

For Single-Output Applications: MAX1653EEE+ and MAX1655EEE+ are suitable alternatives when application requirements permit reduction to single output configuration. Both maintain all critical electrical parameters and active product status. MAX1655EEE+ offers higher inventory availability (4400 pcs) compared to MAX1653EEE+ (2200 pcs).

Compliance and Certification: All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original MAX1652EEE+ specifications. All parts are REACH Unaffected and classified under ECCN EAR99.

Procurement Continuity: The MAX1652EEE+ obsolete status necessitates transition to active alternatives. MAX1655EEE+ provides the highest inventory availability for immediate procurement needs. MAX1654EEE+ provides direct functional equivalence for dual-output designs.

Frequently Asked Questions (FAQ)

Q: Can MAX1653EEE+ or MAX1655EEE+ replace MAX1652EEE+ in a dual-output design? A: No. MAX1653EEE+ and MAX1655EEE+ support only single output configuration. For dual-output applications, MAX1654EEE+ is the required substitute, as it maintains the 2-output specification of the original MAX1652EEE+.

Q: Are all substitute parts pin-compatible with MAX1652EEE+? A: All substitute parts share identical 16-SSOP package geometry (0.154", 3.90mm Width) and surface mount configuration. Pin compatibility must be verified against specific application schematics and PCB layouts, as output configuration differences may affect pin functionality.

Q: What is the difference between the substitute parts? A: The primary difference is output configuration. MAX1654EEE+ maintains 2 outputs matching the original MAX1652EEE+. MAX1653EEE+ and MAX1655EEE+ provide single-output variants. All other electrical parameters, switching frequencies, voltage ranges, and control features remain identical.

Q: Are all substitute parts ROHS3 compliant? A: Yes. MAX1653EEE+, MAX1654EEE+, and MAX1655EEE+ are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original MAX1652EEE+ compliance profile.

Q: Which substitute part has the best inventory availability? A: MAX1655EEE+ offers the highest inventory availability at 4400 pcs. MAX1653EEE+ has 2200 pcs available, and MAX1654EEE+ has 1159 pcs available.

Q: Can I use these substitutes interchangeably in existing designs? A: Substitution depends on application output requirements. For designs requiring dual outputs, only MAX1654EEE+ is suitable. For single-output applications, MAX1653EEE+ or MAX1655EEE+ are acceptable. Circuit design modifications may be required based on output configuration changes.
