11 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
11.1 Application Information
The TPS6103x dc/dc converters are intended for systems powered by a dual or triple cell NiCd or NiMH battery
with a typical terminal voltage between 1.8 V and 5.5 V. They can also be used in systems powered by one-cell
Li-Ion with a typical stack voltage between 2.5 V and 4.2 V. Additionally, two or three primary and secondary
alkaline battery cells can be the power source in systems where the TPS6103x is used.
