TPS61201EVM-179: 3.3V @ up to 1A; 0.5 ~ 5.5V in

Summary

The TPS6120xEVM-179 is specially designed and optimized to operate from a single-cell, two-cell, or three-cell alkaline, NiCd or NiMH, as well as a one-cell Li-Ion or Li-polymer battery. It is also used in single-cell fuel cell or solar cell battery applications where the input voltage is as low as 0.3V.

The TPS6120xEVM-179 operates from a 0.3V to 5.5V (starts up at 0.5V) input rail and provides a single output voltage up to 5.5V.

The TPS6120x is the industry’s lowest input-voltage boost converter, enabling portable electronic end equipment to draw power from new energy sources such as solar and micro-fuel cells.

The TPS6120xEVM-179 has three orderable EVMs:

TPS61200EVM-179 - Adjustable output voltage version preset at 3.3V.
TPS61201EVM-179 - Fixed 3.3V
TPS61202EVM-179 - Fixed 5.0V
