FT440AA

Overview

The FT440AA is a DC-DC switching regulator manufactured by Fremont Micro Devices Ltd. It functions as a step-down converter with a buck topology and positive output configuration. The device provides one adjustable output voltage, starting at a minimum of 0.6V. It operates within an ambient temperature range of -40°C to 85°C. The component is housed in an SC-74A or SOT-753 package.

Feature Summary

Step-down voltage regulation using buck topology
Adjustable positive output configuration
Wide operating temperature range for industrial environments

Applications

Portable electronic devices requiring efficient power conversion
Battery-powered systems needing step-down voltage regulation
Embedded circuits utilizing adjustable low-voltage outputs

Procurement Notes

Verify the part status carefully, as sources indicate this specific model may be obsolete. Confirm package availability in SC-74A or SOT-753 formats. Ensure compatibility with existing board layouts before procurement. Check for alternative active components if supply continuity is required for long-term production.

Selection Notes

Select this component when a compact buck converter with adjustable output is needed. Consider the limited input voltage range starting at 2.5V. Evaluate thermal performance within the specified -40°C to 85°C range. Verify that the small form factor fits the design constraints.

Part Context

This regulator belongs to the PMIC family from Fremont Micro Devices. It is designed for space-constrained applications requiring efficient DC-DC conversion. The adjustable output allows flexibility in system design. The component supports standard surface-mount assembly processes.
