MAX1652EEE Buck Regulator Controller Equivalent & Substitute Parts

Part Overview

The MAX1652EEE is a buck regulator positive output step-down DC-DC controller IC in 16-QSOP packaging, manufactured by Analog Devices Inc./Maxim Integrated. This component functions as a transistor driver for step-down topology applications with dual output capability. The MAX1652EEE is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support. Substitute parts must maintain electrical compatibility across supply voltage, switching frequency, duty cycle, and output configuration parameters while meeting current RoHS and REACH compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX1652EEE is determined by strict parametric matching across the following critical criteria:

Mandatory Matching Parameters:

• Voltage Supply Range: 4.5V ~ 30V
• Switching Frequency: 150kHz, 300kHz
• Duty Cycle Maximum: 98%
• Output Type: Transistor Driver
• Function: Step-Down
• Output Configuration: Positive
• Synchronous Rectifier: Yes
• Clock Sync: Yes
• Control Features: Enable, Soft Start
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 16-SSOP (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Variable Parameters (Non-Critical for Substitution):

• Number of Outputs: 1 or 2 (application-dependent)
• Product Status: Active substitutes preferred over obsolete
• RoHS Compliance: ROHS3 Compliant preferred
• Packaging Format: Tube acceptable

All three substitute parts (MAX1653EEE+, MAX1654EEE+, MAX1655EEE+) meet these mandatory electrical and mechanical parameters, enabling direct substitution based on output configuration requirements.

Engineering Selection Recommendations

For Dual Output Applications (2 Outputs Required): Select MAX1654EEE+ as the direct functional equivalent to MAX1652EEE. This part maintains identical output configuration (2 outputs) while offering active product status and ROHS3 compliance. The MAX1654EEE+ is manufactured by the same supplier and packaged in tube format for production environments.

For Single Output Applications (1 Output Required): Choose between MAX1653EEE+ or MAX1655EEE+ based on inventory availability and supply chain requirements. Both parts are active, ROHS3 compliant, and functionally equivalent for single-output buck regulator controller applications. MAX1655EEE+ offers higher inventory levels (4400 pcs) compared to MAX1653EEE+ (2200 pcs).

Compliance Considerations: All substitute parts achieve ROHS3 compliance, addressing the non-compliant status of the obsolete MAX1652EEE. This upgrade is mandatory for new designs subject to RoHS Directive 2011/65/EU requirements. REACH status remains unaffected across all parts.

Package and Mounting Compatibility: All substitute parts maintain identical 16-SSOP surface mount packaging (0.154", 3.90mm width), ensuring direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX1653EEE+ or MAX1655EEE+ replace MAX1652EEE in designs requiring dual outputs? A: No. MAX1653EEE+ and MAX1655EEE+ are single-output controllers (1 output). Applications requiring dual outputs must use MAX1654EEE+, which maintains the 2-output configuration of the original MAX1652EEE.

Q: Are all substitute parts pin-compatible with MAX1652EEE? A: All substitute parts share identical 16-QSOP packaging and 16-SSOP case dimensions. Pin compatibility is determined by the specific output configuration (1 or 2 outputs) required by your application. Consult device datasheets for detailed pinout verification.

Q: What is the impact of switching from MAX1652EEE to an active substitute part? A: The primary change is product status transition from obsolete to active, ensuring long-term availability and supply chain stability. All substitute parts maintain identical electrical specifications (supply voltage, switching frequency, duty cycle, control features) and operating temperature range. RoHS3 compliance of substitute parts represents an improvement over the non-compliant original part.

Q: Which substitute part offers the best inventory availability? A: MAX1655EEE+ provides the highest inventory level at 4400 pcs. For dual-output requirements, MAX1654EEE+ is available with 1159 pcs in stock.

Q: Are there any thermal or performance differences between MAX1652EEE and the substitute parts? A: All parts operate across the identical temperature range (-40°C ~ 85°C) and maintain the same switching frequency options (150kHz, 300kHz) and maximum duty cycle (98%). Performance characteristics remain equivalent across the substitute family.

Q: Can I use substitute parts in existing MAX1652EEE designs without PCB modifications? A: Yes, for the appropriate output configuration. The 16-SSOP package dimensions and surface mount footprint are identical. Verify output configuration requirements (1 or 2 outputs) and select the corresponding substitute part. No PCB layout changes are required.
