TPS61150EVM-150: 15mA x2 @ 17.4V Max, 2.5 ~ 6V in
Summary
The Texas Instruments TPS61150EVM-150 evaluation module contains the TPS61150 IC. This EVM provides 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.
Changing components can improve or degrade EVM performance. For example, using inductors with 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.
