This simplifies to (IHVLED1 (or IHVLED2) – IHVLED(AVE))/(IHVLED(AVE)) × 100. In this test, both HVLED1 and HVLED2 are assigned to Bank A. (2) LED current sink matching in the low-voltage current sinks (LVLED1 through LVLED5) is given as the maximum matching value between any two current sinks, where the matching between any two low voltage current sinks (X and Y) is given as (ILVLEDX (or ILVLEDY) – IAVE(X-Y))/(IAVE(X-Y)) × 100. In this test all LVLED current sinks are assigned to Bank C. Copyright © 2012–2015, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: LM3533 |
