MAX630CSA+ Equivalent & Substitute Parts

Part Overview

The MAX630CSA+ is a boost switching regulator IC manufactured by Analog Devices Inc./Maxim Integrated, designed for step-up voltage conversion applications. This positive adjustable output device operates with an input voltage range of 2.2V to 16.5V and delivers up to 525mA output current at a fixed switching frequency of 40kHz. The component is currently in active production status and is widely used in portable power applications, battery charging circuits, and low-voltage to higher-voltage conversion systems where compact surface-mount packaging is required.

The necessity to identify equivalent and substitute parts arises from supply chain considerations, inventory availability, and design flexibility requirements in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX630CSA+ is determined by strict alignment with the following critical parameters:

Functional Requirements:

• Topology: Boost (step-up) switching regulator
• Output Configuration: Positive adjustable
• Number of Outputs: Single output

Electrical Specifications:

• Input Voltage Range: 2.2V minimum to 16.5V maximum
• Output Voltage Range: 2.2V minimum to 18V maximum
• Output Current Capability: 525mA (switch current)
• Switching Frequency: 40kHz

Physical & Environmental Requirements:

• Package Type: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: 0°C to 70°C
• Synchronous Rectifier: Not required

Compliance Requirements:

• RoHS3 Compliance
• Active product status

Only components meeting all of these parameters simultaneously qualify as direct substitutes. Deviations in any single parameter disqualify a component from substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

The MAX630CSA+ is an active product with full ROHS3 compliance, ensuring long-term availability and regulatory conformance for industrial and commercial applications. Selection of substitute components must maintain identical compliance certifications and active product status to ensure supply chain continuity and regulatory adherence.

When evaluating alternatives, confirm that the substitute component carries the same RoHS3 compliance designation and maintains active production status. The 8-SOIC package format is standard for this device class and ensures compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX630CSA+?

A: A valid substitute must match all critical parameters: boost topology, positive adjustable output, single output configuration, 2.2V to 16.5V input range, 2.2V to 18V output range, 525mA output current, 40kHz switching frequency, 8-SOIC package, surface mount mounting type, 0°C to 70°C operating temperature, and ROHS3 compliance with active product status.

Q: Can components with different switching frequencies be substituted?

A: No. The switching frequency of 40kHz is a critical parameter that affects circuit performance, EMI characteristics, and component selection for external inductors and capacitors. Substitutes must maintain this specification.

Q: Are different package types acceptable as substitutes?

A: No. The 8-SOIC (0.154", 3.90mm Width) package is a specific requirement. Different package types have different pin configurations, thermal characteristics, and PCB footprints, making them incompatible with existing designs.

Q: What is the significance of the adjustable output type?

A: The adjustable output type allows the output voltage to be set within the 2.2V to 18V range through external resistor networks. Substitutes must maintain this adjustability to preserve design flexibility.

Q: Does RoHS3 compliance affect substitution eligibility?

A: Yes. RoHS3 compliance is a mandatory requirement for substitutes to ensure regulatory conformance and long-term material availability. Components without this certification are not acceptable alternatives.

Q: Is synchronous rectification a requirement for substitution?

A: No. The MAX630CSA+ does not include a synchronous rectifier, and substitutes are not required to include this feature. However, substitutes with synchronous rectification may be considered if all other parameters remain identical.
