MP3435GL-Z Equivalent & Substitute Parts

Part Overview

The MP3435GL-Z is an active boost switching regulator integrated circuit manufactured by Monolithic Power Systems Inc. This device functions as a step-up (boost) converter with positive adjustable output, designed for applications requiring voltage regulation from a lower input voltage to a higher output voltage. The IC operates with a 19A switch current capability and 600kHz switching frequency, incorporating a synchronous rectifier for improved efficiency.

The MP3435GL-Z is classified as an active product with full RoHS3 compliance and REACH unaffected status. Identification of equivalent and substitute parts is necessary for supply chain continuity, design flexibility, and procurement optimization when the primary part number becomes unavailable or when alternative sourcing is required.

• Input Voltage Range: 3V to 20V
• Output Voltage Range: 3V to 22V
• Switch Current: 19A
• Switching Frequency: 600kHz
• Synchronous Rectifier: Present

Mechanical & Environmental Specifications:

• Mounting Type: Surface Mount
• Package Type: 20-PowerVFQFN (20-QFN 3x4)
• Operating Temperature Range: -40°C to 125°C (TJ)

Compliance & Status:

• Product Status: Active

Engineering Selection Recommendations

The MP3435GL-Z is an active product with full regulatory compliance. Selection of equivalent parts is based on the following criteria:

Product Status Alignment: Both the main part and substitute maintain active product status, ensuring ongoing manufacturer support and availability of technical documentation.

Regulatory Compliance: All substitute parts must maintain ROHS3 compliance and REACH unaffected status to satisfy environmental and regulatory requirements in target markets.

Certification & Reliability: Moisture Sensitivity Level 1 (Unlimited) indicates no moisture-related handling restrictions. This specification must be maintained in substitute parts to ensure equivalent reliability and shelf-life characteristics.

Electrical & Mechanical Compatibility: Substitutes must match all electrical parameters (input/output voltage ranges, switch current, switching frequency, synchronous rectifier presence) and mechanical specifications (20-PowerVFQFN package, surface mount configuration, operating temperature range) to ensure direct functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MP3435GL-Z?

A: A valid substitute must match all electrical specifications (boost topology, 19A switch current, 600kHz switching frequency, 3V-20V input, 3V-22V output, synchronous rectifier), mechanical specifications (20-PowerVFQFN package, surface mount), operating temperature range (-40°C to 125°C), and compliance status (ROHS3, REACH unaffected, MSL 1).

Q: Can the MP3435GL-Z be replaced with a different package variant?

A: No. The 20-PowerVFQFN (20-QFN 3x4) package is a critical specification. Different package types have different pin configurations, thermal characteristics, and PCB footprints, making them incompatible for direct substitution.

Q: Are there any parametric equivalents with different switching frequencies?

A: No. The 600kHz switching frequency is a fixed specification of the MP3435GL-Z. Substitutes with different switching frequencies are not equivalent and do not qualify as valid replacements.

Q: What is the significance of the synchronous rectifier specification?

A: The synchronous rectifier is an integrated component that improves efficiency by reducing conduction losses. Substitutes must include this feature to maintain equivalent performance characteristics and efficiency levels.

Q: Does the MSL 1 (Unlimited) rating affect substitution?

A: Yes. MSL 1 indicates unlimited shelf life without moisture baking requirements. Substitutes with higher MSL ratings (2, 3, etc.) have different handling and storage requirements and are not equivalent.

Q: Can the MP3435GL-Z be used in applications requiring fixed output voltage?

A: The MP3435GL-Z has adjustable output type, allowing configuration for various output voltages within the 3V-22V range. Applications requiring fixed output voltage require external resistor divider networks for feedback configuration.

Q: Is the MP3435GL-Z suitable for input voltages below 3V?

A: No. The minimum input voltage specification is 3V. Operation below this threshold is outside the device's rated operating range and is not supported.

Q: What is the maximum output current capability?

A: The switch current is rated at 19A. Actual output current depends on the specific application topology, duty cycle, and thermal management implementation.
