- Portable electronic devices requiring compact boost regulation
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status before integration, as the component may be subject to discontinuation notices. Confirm that the 5-lead SOT-23 footprint matches the design layout. Ensure the 30V output rating aligns with the target load requirements and that the 65mA drive capability meets the circuit's current demands.
Selection Notes
Select this component when a compact solution is required for driving OLED or LED displays with integrated boost regulation. The 3-in-1 dimming feature offers flexibility for various control schemes. Ensure the input voltage does not exceed 5.5V and that the thermal environment stays within the -40°C to +85°C operational range for reliable performance.
Part Context
This part belongs to the FAN5333A series of display drivers from onsemi. It is categorized under Power Management ICs (PMIC) and specifically serves as a switching voltage regulator. The device is designed to replace discrete solutions by integrating the boost converter and driver into a single small-footprint package.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative components based on pinout, electrical specifications, and package dimensions.
