Description

The TPS6128xD/E 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 TPS6128xD/E extends the battery run-time and overcomes input current- and voltage limitations of the powered system.

While in shutdown, the TPS6128xD/E operates in a true pass-through mode with only 3-µA 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 uses the full battery capacity.
