MAX1626ESA+

DC DC Switching Controllers Overview

The MAX1626ESA+ is a switching controller designed for generating 5V, 3.3V, or adjustable output voltages from a single Li-ion battery source. It operates with a fixed 100% duty cycle to minimize input current requirements during high-load conditions. The device integrates an N-channel power switch and supports external MOSFETs for higher current applications. It features a low quiescent current of 45µA in shutdown mode and includes thermal shutdown protection. The component is housed in an 8-pin SOIC package.

DC DC Switching Controllers Feature Summary

DC DC Switching Controllers Procurement Notes

Verify the specific suffix and tape/reel versus tube packaging options available through authorized distributors. Confirm RoHS compliance status and lead times directly with Analog Devices or certified partners, as availability may vary. Ensure the ordering part number matches the required package type and temperature range specifications for your design.

DC DC Switching Controllers Selection Notes

Select this component when designing circuits powered by single-cell lithium-ion sources that require efficient step-up conversion. It is suitable for applications where minimizing input current is critical. Consider external MOSFETs if the load current exceeds the capabilities of the internal switch. Verify that the operating temperature range meets the environmental requirements of the target application.
