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 ≥ 0.5V) input rail and
provides a single output voltage up to 5.5V.
The TPS6120xEVM-179 has three orderable EVMs shown in
