LED Driver IC Procurement Notes

Verify component authenticity through authorized MPS distributors or certified partners. Confirm the specific suffix 'Z' indicates RoHS compliance and lead-free status. Check current availability as supply may be limited or subject to factory special orders. Ensure the SOT-583-8 package matches your PCB footprint requirements before finalizing procurement.

LED Driver IC Selection Notes

Select this component when designing circuits requiring a 24V input capable LED driver with 1 MHz switching frequency. It is suitable for space-constrained applications due to the SOT-583-8 package. Consider its 2A current limit for WLED arrays. Compare against the MP2328CGTL-Z if lower current (1A) and different input voltage ranges are sufficient for the design.

LED Driver IC Part Context

This part belongs to the MP2341 series of high-efficiency synchronous step-down LED drivers. It is designed specifically for driving white LED arrays in portable and display applications. The series emphasizes high efficiency and compact size, utilizing integrated MOSFETs to reduce external component count compared to discrete solutions.

LED Driver IC Replacement Considerations

The MP2328CGTL-Z is a related component within the same family but offers 1A capacity and a 22V output limit. Verify if the reduced current rating meets application needs. No other direct public substitutes are confirmed in the provided documentation.
