The TLV61290 provides a power supply solution for products powered by a nickel-rich, silicon anode, Li-ion or LiFePO4 battery. The voltage range is optimized for single-cell portable applications like in smart-phones or POS terminal.

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 2.0V to 5.0V. Program the output voltage by I2C up to 5.0V, and the default output voltage is 3.4V.

During operation, when the battery is in a good state of charge, the TLV61290 will work in bypass mode, connecting the battery to the power supply system through the bypass FET. 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 use the full battery capacity.

The TLV61290 offers a very small solution size with 16-ball YBG package.
