Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and qualification grade. Ensure that the ordering suffix accurately reflects the required reel or cut tape packaging configuration. Cross-reference the part number with the latest datasheet to validate compatibility with your system's voltage and current requirements before procurement.

Selection Notes

Select this component when designing industrial-grade LED drivers requiring a 1.5 A output capability and a 36 V maximum input voltage. The 2.2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the QFN-13 package for space-constrained PCB layouts while ensuring adequate thermal management due to the power dissipation characteristics.
