Procurement Notes
Verify the specific datasheet version, as product change notices may affect specifications. Confirm the package marking and pinout alignment with your PCB footprint. Check for end-of-life status or alternative recommendations from the manufacturer. Ensure compliance with RoHS and REACH requirements for your target market. Validate thermal performance under maximum load conditions.
Selection Notes
Choose this component when a single IC must handle both buck and boost operations for LED strings. Consider the 14-SOP package constraints for board space. Evaluate the required dimming method compatibility with your system controller. Assess the operating temperature range against environmental conditions. Verify that the input voltage range matches your available power rails.
Part Context
This part belongs to the RT8496 family of LED drivers from Richtek. It is designed for high-performance power management in lighting applications. The series focuses on efficiency and flexibility in driving LED loads. Other variants in the family may offer different pin counts or voltage ratings.
Replacement Considerations
