The device powers a single series string of LEDs with output voltages of up to 40 V and a peak inductor current of typically 839 mA. The input active voltage range is from 2.7 V to 5.5 V. 8.2 Functional Block Diagram Copyright © 2009–2014, Texas Instruments Incorporated Submit Documentation Feedback 11 Product Folder Links: LM3530 |
