1.4 Device Information

The TPS61290x device provides a power supply design for products powered by either by a Li-Ion, Nickel-Rich, Silicon Anode, or LiFePO4 battery. The voltage range is optimized for single-cell portable applications like in smartphones or tablet PCs. Used as a high-power pre-regulator, the device extends the battery run-time and overcomes input current and voltage limitations of the powered system. With a wide input voltage range of 1.8V to 5.5V, the device supports applications powered by Li-Ion batteries with extended voltage range. The output voltage can be programmed by I2C up to 5.5V. During operation, when the battery is at a good state-of-charge, a low-ohmic, high-efficient integrated pass-through path (from a by-pass FET) connects the battery to the powered system. If the battery gets to a lower state of charge and the voltage becomes lower than the desired minimum system voltage, the device seamlessly transits into boost mode to uses the full battery capacity.

The TPS61290x offers a very small design size with a 16-ball WCSP package.
