TPS63700EVM-139: -12V @ 200mA, 2.7 ~ 5.5 Vin

Summary

The Texas Instruments TPS63700EVM-139 evaluation module uses a TPS63700 dc/dc inverter IC that is capable of providing a negative output power supply from a positive input voltage. The goal of the EVM is to facilitate evaluation of the TPS63700.

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.
