Procurement Notes
Verify the specific suffix ASP-13 against official Diodes Incorporated documentation to confirm the SOIC-8 package and reel/cut-tape availability. Ensure compatibility with the required 85-277 VAC input range and 300 kHz switching frequency for the target design. Cross-reference the RoHS status and operating temperature limits (-40°C to +105°C) with system requirements before finalizing procurement.
Selection Notes
Select this component for designs requiring a single-channel, non-isolated LED driver with universal AC input capabilities. The SOIC-8 package suits space-constrained surface-mount applications. Consider the 300 kHz frequency and 2.2 W power dissipation when designing thermal management and EMI filtering strategies. Verify that the boost/buck topology aligns with the specific LED string configuration and voltage requirements of the application.
Part Context
The AL9910ASP-13 belongs to the AL99 series of LED drivers manufactured by Diodes Incorporated. This series focuses on high-brightness LED applications using universal high-voltage inputs. The part integrates control logic and power stages into a compact surface-mount package, simplifying the design of efficient AC-powered lighting fixtures compared to discrete solutions.
Replacement Considerations
Consult official Diodes Incorporated substitution guides for verified alternatives. Generic cross-references may not match the specific 300 kHz frequency or pinout configuration.
