Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'ES' against official documentation, as primary sources predominantly list the 'CSA' variant. Confirm RoHS compliance status and lead times directly with Analog Devices or authorized distributors, as availability varies by region. Ensure the ordering information matches the exact package and temperature grade required for your design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, low-cost boost converter is needed for inputs starting at 2V. The 450mA switch current capability suits moderate load applications. Consider the 8-SOIC package constraints for thermal management. Verify that the fixed 1.31V option meets system requirements if adjustable outputs are not necessary.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX641 series of CMOS step-up regulators. These devices are designed for battery-operated applications where efficiency and low component count are critical. The series typically integrates the power switch and control logic into a single compact package to minimize external component requirements.
