MAX742CPP

Overview

The MAX742CPP is a switch-mode regulator controller designed for dual-output power supplies in the 3W to 60W range. It operates with an input voltage range of 4.2V to 10V and provides output voltages of ±12V or ±15V. The device supports load currents up to ±2A and features current-mode control with pulse width modulation. It utilizes simple two-terminal inductors instead of transformers, offering ±4% output tolerance maximum over temperature and line variations.

Feature Summary

• Dual-output switching regulator controller architecture
• Logic-controlled switching between ±15V and ±12V outputs
• Current-mode control technique for stable regulation
• Transformer-less design using two-terminal inductors

Applications

• Dual-rail power supply systems
• Analog circuit biasing requiring positive and negative rails
• Low-power industrial equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'CPP' indicates the 20-pin DIP package variant when sourcing. Confirm that the component meets RoHS compliance requirements if necessary, as some Maxim Integrated products from this era may not be compliant. Ensure the supplier provides valid traceability documentation for analog integrated circuits.

Selection Notes

Select this component when a compact, transformer-less solution for dual polarity outputs is required. It is suitable for applications needing logic-controllable output voltage levels. Consider the 20-pin DIP package for through-hole mounting needs. Evaluate the 4.2V to 10V input range against system power availability.

Part Context

This part belongs to the MAX742 family of switch-mode regulators manufactured by Maxim Integrated, now part of Analog Devices Inc. The series focuses on efficient power conversion without traditional magnetics. The CPP suffix specifically denotes the plastic dual-in-line package configuration, distinguishing it from surface-mount variants like the WWP.

Replacement Considerations

Check for direct pin-compatible replacements within the MAX742 family. Verify functional equivalence regarding input voltage range and output current capabilities. Consult manufacturer cross-reference lists for updated components with improved environmental compliance.
