Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix and tape-and-reel packaging configuration against the official datasheet before ordering. Confirm that the 10-MSOP footprint matches your PCB layout requirements. Ensure the operating temperature range aligns with your system's environmental conditions. Cross-reference the manufacturer part number to avoid confusion with similar variants in the LTC3401 family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an application requires boosting very low input voltages, such as those from depleted batteries, to a stable higher level. The 2MHz switching frequency allows for the use of small inductors and capacitors, saving board space. Consider the 1A switch current limit to ensure it meets the load requirements without exceeding thermal limits in the MSOP package.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LTC3401 series of micropower synchronous boost converters. It is designed for applications where space is limited and efficiency is critical. The series typically includes variants with different fixed output voltages or adjustable settings, all sharing the same core architecture and pinout compatibility within the MSOP package.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for other LTC3401 variants with different output voltages if the 2.6V fixed output does not match the design requirement. Verify compatibility with alternative synchronous boost regulators from Analog Devices or other manufacturers, ensuring pinout and electrical specifications align.
