User's Guide for TPS61183EVM-528

and TPS61187EVM-528

This user's guide describes the characteristics, operation, and use of the TPS61183 evaluation module

(EVM). This EVM 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/laptop

computers. This user's guide includes EVM specifications, recommended test setup, test results, bill of

materials, and a schematic diagram.
