9.1 Application Information

With a wide input voltage range of 2.5 V to 5.5 V, the TPS61256A supports applications powered by Li-Ion batteries with extended voltage range. Intended for low-power applications, it supports up to 800-mA load current from a battery discharged as low as 2.7 V and allows the use of low cost chip inductor and capacitors. Different fixed voltage output versions are available from 3.15 V to 5.0 V. The TPS61256A offers a very small solution size due to minimum amount of external components. It allows the use of small inductors and input capacitors to achieve a small solution size. During shutdown, the load is completely disconnected from the battery.
