The TPS61181AEVM-259 user's guide describes the characteristics, operation, and use of the TPS6118xEVM-259 evaluation module (EVM). This EVM contains either Texas Instruments' TPS61181 (-001 build) or TPS61182 (-002 build) or TPS61181A (-003 build)-based WLED power solutions, each of which provides up to six independently regulated current outputs using a single inductor step-up (boost) converter. The current outputs are ideal for driving a WLED backlight in notebook/laptop computers. A separate EVM, WLEDEVM-260, contains eight strings of 10 series WLEDs and connects to the TPS6118x EVMs via a 14-pin ribbon cable to simplify evaluation. This user's guide includes EVM specifications, recommended test setup, test results, bill of materials, and a schematic diagram for the TPS61181/2/1AEVM.
