Texas Instruments TPS81256EVM Evaluation Module
Texas Instruments TPS81256EVM Evaluation Module enables test and evaluation of the TPS81256 high-efficiency step-up converter. This converter provides a complete MicroSiP DC/DC step-up power solution intended for battery-powered portable applications. The TPS81256EVM module is designed to produce a fixed output voltage over the full input voltage range. A DC power supply capable of delivering 2.5V to 4.85V is required to operate this evaluation module. The TPS81256EVM evaluation module is used in USB-host and charging-port power supplies, general Li‑ion battery‑powered systems, portable audio devices, and RF power‑amplifier buffer applications.
