The TPS6128x device provides a power supply solution for products powered by either by a
Li-Ion, Nickel-Rich, Silicon Anode, Li-Ion or LiFePO4 battery. The voltage range is optimized for
single-cell portable applications like in smart-phones or tablet PCs.
Used as a high-power pre-regulator, the TPS6128x extends the battery run-time and
overcomes input current- and voltage limitations of the powered system.
While in shutdown, the TPS6128x operates in a true pass-through mode with only 2µA
quiescent consumption for longest battery shelf life.
During operation, when the battery is at a good state-of-charge, a low-ohmic,
high-efficient integrated pass-through path connects the battery to the powered system.
If the battery gets to a lower state of charge and its voltage becomes lower than the
desired minimum system voltage, the device seamlessly transits into boost mode to utilize the full
