TPS61280YFFR Datasheet PDF - TI

●DESCRIPTION

●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.
