The TPS61183/7EVM-528 evaluation module contains Texas Instruments' either the TPS61183 or TPS61187 IC configured as a WLED power solution providing 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/laptopcomputers. This user's guide includes EVM specifications, recommended test setup, test results, bill of materials, and a schematic diagram.
