Introduction
The Texas Instruments TPS61150EVM-150 evaluation module contains a TPS61150 IC while the
TPS61150AEVM-150 evaluation module contains a TPS61150A IC. Both EVMs provide two
independently regulated current outputs using a single inductor step-up (boost) converter. One output
drives two parallel strings of WLEDs. One string can be configured for two or four series WLEDs. The
other string has four series WLEDs. The goal of these EVMs is to facilitate evaluation of the TPS61150 or
TPS61150A IC in a typical WLED application.

To aid user customization of the EVM, the board was designed with devices having 0603 or larger
footprints. A real implementation would likely occupy less total board space.
footprints. A real implementation would likely occupy less total board space.
Changing components can improve or degrade EVM performance. For example, using inductors with
larger dc resistances lowers efficiency of the solution.
larger dc resistances lowers efficiency of the solution.
The TPS61151 IC has the same pin out as the TPS61150. Therefore, it can be installed and evaluated on
this EVM board.
