Procurement Notes
Verify the specific suffix 'GR' against the manufacturer's latest datasheet to confirm packaging details, such as reel or cut tape specifications. Ensure the order quantity aligns with standard packaging units defined by Diodes Incorporated. Confirm RoHS3 compliance status if required for your assembly process. Cross-reference the 8-DFN footprint dimensions during PCB layout finalization.
Selection Notes
Select this component when a compact solution for driving multiple series-connected white LEDs is required. The 1.5A current rating suits applications needing moderate brightness levels. The wide input voltage range allows compatibility with single-cell lithium battery sources. Consider the 40V output limit to ensure it matches the forward voltage requirements of the target LED string configuration.
Part Context
This part belongs to the PAM2841 series of LED drivers from Diodes Incorporated. The series focuses on providing regulated current for white LEDs in space-constrained environments. The GR suffix typically denotes the specific tape-and-reel packaging variant used for automated surface-mount assembly processes.
Replacement Considerations
Consult the official Diodes Incorporated cross-reference documentation for verified substitute part numbers. Do not assume functional equivalence with other boost converters without verifying pinout and electrical parameter alignment.
