TPS61020EVM-025: Boost, 3.3V @ 250 ~ 900mA, 0.9 ~ 6V in

Summary

The Texas Instruments TPS61020 evaluation module (EVM) for low-power, high-efficiency, boost converter helps designers evaluate the TPS61020 device. The EVM makes it possible to evaluate different device modes as well as the device performance.

The TPS61020EVM is set to 3.3 V. It can be easily set up to provide any output voltage between 1.8 V and 5.5 V by adjusting the external resistor divider. Refer to the datasheet (SLVS451) for the output voltage calculation. The TPS61020 has an input voltage range between 0.9 V and 6.5 V.
