MAX722CSE

Overview

The MAX722CSE is a dual-output switching regulator IC designed for portable applications. It integrates two DC-DC converters within a single 16-SOIC package. The device accepts an input voltage range of 7V to 20V. One output provides a fixed 5V supply, while the second output is adjustable from 0V to 3.3V or up to 100V depending on configuration. Operating temperature is specified from 0°C to 70°C.

Feature Summary

• Integrates dual independent DC-DC converters in a compact surface-mount package
• Supports wide input voltage range suitable for battery-powered systems
• Provides flexible output configurations including fixed and adjustable rails

Applications

• Palmtop computer power management
• LCD bias voltage generation
• Portable converter circuits

Procurement Notes

Verify component authenticity through authorized channels as counterfeit integrated circuits exist. Confirm RoHS compliance status carefully; some listings indicate non-compliance while others suggest active status with different suffixes. Check datasheet revisions for electrical parameter updates before integration into final designs.

Selection Notes

Select this component when dual isolated or non-isolated outputs are required from a single high-voltage source. Ensure thermal management capabilities match the application's power dissipation requirements. Verify that the 16-SOIC footprint fits the PCB layout constraints compared to alternative packages.

Part Context
