Page 5: Introduction
SNVU509 – January 2016 LM36923HEVM User's Guide Introduction The Texas Instruments LM36923HEVM evaluation module (EVM) helps designers evaluate the operation and performance of the LM36923H Highly Efficient Triple-String White LED driver. The device offers configurability via I C-compatible interface. The EVM contains six dual-LED and a single LED per string which can be easily configured to support 1, 2 or 3 parallel LED strings with 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 or 13 series LEDs. -
