Procurement Notes
Verify the specific suffix 'S30' against official datasheets to confirm pinout and electrical characteristics, as variations exist within the FAN5345 family. Confirm availability status directly with onsemi or authorized distributors, as lead times and stock levels fluctuate. Ensure the selected package matches the PCB footprint requirements for SuperSOT-6 components.
Selection Notes
Select this component for designs requiring a compact, single-channel boost driver with digital control. It is suitable for battery-powered applications due to its low quiescent current and small package. Compare against other FAN5345 variants if different output currents or interface options are needed. Ensure the input voltage range aligns with the system power supply.
Part Context
This part belongs to the FAN5345 series of LED drivers designed for portable electronics. The series focuses on minimizing board space through high-frequency operation and integrated solutions. The FAN5345S30X specifically targets applications needing precise current control and digital dimming in a minimal footprint.
Replacement Considerations
Check for direct substitutes within the FAN5345 family, such as the FAN5345S20X, ensuring functional compatibility regarding output current and interface. Verify pin-to-pin compatibility before substitution.
