TPS61185EVM-335
This user's guide describes the characteristics, operation, and use of the TPS61185 evaluation module
(EVM). This EVM contains the Texas Instruments TPS61185, a WLED power solution providing up to
eight 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. This user's guide
includes EVM specifications, recommended test setup, bill of materials, and a schematic diagram.
