LED Driver IC Procurement Notes

Verify the specific suffix #WTRPBF indicates tape-and-reel packaging when ordering. Confirm that the -1 variant matches the required pinout and functional specifications against the official Analog Devices datasheet. Ensure compatibility with the target PCB footprint for the 16-lead QFN-4x4 package. Check for any regional distribution restrictions or obsolescence notices prior to final procurement decisions.

LED Driver IC Selection Notes

Select this component when a wide input voltage range up to 60 V is required for single-string LED applications. The 2 MHz fixed frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the AEC-Q100 qualification if the application demands automotive-grade reliability. Evaluate thermal performance requirements based on the 1.2 A output current capability within the specified QFN package constraints.
