I need to drive one white LED with regulated current at 1 of 3 microcontroller-selectable levels: 10, 90 or 800 mA. Input may be as low as 2.4V. The closest we've come is starting with a T.I. TPS63000 and then adding ckty to sense current and apply voltage representing it to the feedback pin of that regulator. Would like to find a more integrated and lower cost solution.

We do not offer an exact match according your specification however you might consider our NCP5030, the datasheet http://www.onsemi.com/pub_link/Collateral/NCP5030-D.PDF for more details. Please let me know if you have any other questions. Answered by:
