- Low voltage LED arrays
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or product change notification. Ensure the procurement channel sources genuine components to avoid counterfeit risks associated with SMD/SMT packages.
Selection Notes
Select this component when a linear topology is preferred for simplicity and low noise in high-power LED applications. It is suitable for designs requiring a 1.5 A drive current with an input voltage limited to 6 V. Consider the thermal dissipation requirements inherent to linear regulators when designing the PCB layout for sustained operation at maximum current.
Part Context
This part belongs to the PAM28 series of LED drivers manufactured by Diodes Incorporated. It is designed specifically for high-power applications, distinguishing it from lower-current general-purpose drivers. The BLBR suffix indicates the specific surface-mount packaging configuration provided by the manufacturer.
Replacement Considerations
The PAM2841GR is a related component within the same family but utilizes a boost converter topology rather than linear regulation. Engineers must evaluate the difference in efficiency and input voltage requirements when considering cross-family substitutions.
