Procurement Notes
Verify the specific manufacturer source, as the part number appears under both Fairchild Semiconductor and onsemi due to corporate acquisition history. Confirm the exact datasheet version matches the required electrical specifications. Check for any obsolescence notices or lifecycle status changes from the current supplier. Ensure the package marking aligns with the SOT-23-5 form factor. Validate RoHS compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when a compact solution is needed for driving high-current LEDs or OLED panels from a single-cell lithium battery source. The integrated switch eliminates external inductor requirements typical of boost converters, simplifying the PCB layout. Consider the 1.5A current limit and 30V voltage rating to ensure compatibility with the load requirements. The SOT-23-5 package is suitable for space-constrained portable electronics designs.
Part Context
This device belongs to the FAN5332 family of LED drivers designed for portable applications. It combines the driver logic and power switch into a single small footprint. The series is intended for applications requiring efficient power management and precise light output control in mobile and consumer electronic devices.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided data. Verify functional compatibility with alternative LED drivers offering similar current ratings and package types.
