MAX756CSA Equivalent & Substitute Parts

Part Overview

The MAX756CSA is a Boost Switching Regulator IC manufactured by Analog Devices Inc./Maxim Integrated, designed for positive programmable output voltage regulation at 3.3V or 5V. This device functions as a step-up converter with a single programmable output, operating from input voltages between 0.7V and 7V. The MAX756CSA is classified as obsolete, which necessitates identification of equivalent substitute components for new designs or production continuity.

Substitute Part Grouping Explanation

Substitution of the MAX756CSA is determined by strict equivalence across the following critical parameters:

  • Topology & Function: Boost switching regulator with step-up conversion capability
  • Output Configuration: Positive, programmable output voltage
  • Voltage Specifications: Input range 0.7V to 7V; output selectable at 3.3V or 5V
  • Switching Frequency: 500kHz operation
  • Package: 8-SOIC form factor (0.154", 3.90mm Width)
  • Mounting: Surface mount technology
  • Rectifier Type: Non-synchronous design

The MAX756CSA+ qualifies as a direct substitute based on identical electrical specifications, package configuration, and functional characteristics. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The MAX756CSA+ is the direct equivalent substitute for the MAX756CSA. Both devices share identical electrical specifications, functional characteristics, and package configuration. The MAX756CSA+ is preferred for new designs and production applications due to its active product status and ROHS3 compliance certification. The obsolete status of the MAX756CSA makes the MAX756CSA+ the appropriate selection for design continuity and regulatory compliance in applications requiring RoHS adherence.

Frequently Asked Questions (FAQ)

Q: Can MAX756CSA+ be used as a direct replacement for MAX756CSA?

A: Yes. The MAX756CSA+ is electrically and mechanically equivalent to the MAX756CSA. Both devices operate identically across all specified parameters including input voltage range (0.7V to 7V), programmable output voltage (3.3V or 5V), switching frequency (500kHz), and 8-SOIC package configuration.

Q: What is the primary difference between MAX756CSA and MAX756CSA+?

A: The MAX756CSA+ is an active product with ROHS3 compliance certification, while the MAX756CSA is obsolete and RoHS non-compliant. Functionally and electrically, both devices are identical.

Q: Are there any package or pinout differences?
