The TPS61256xC device provides a power supply solution for battery-powered portable applications. Intended for low-power applications, the TPS61256xC supports up to 800-mA load current from a battery discharged as low as 2.65 V and allows the use of low cost chip inductor and capacitors.

With a wide input voltage range of 2.3 V to 5.5 V, the device supports applications powered by Li-Ion batteries with extended voltage range. Different fixed voltage output versions are available from 3.15 V to 5.0 V.

The TPS61256xC operates at a regulated 3.5-MHz switching frequency and enters power-save mode operation at light load currents to maintain high efficiency over the entire load current range. The PFM mode extends the battery life by reducing the quiescent current to 37 µA (typ) during light load operation.

In addition, the TPS61256xC device can also support the pass-through mode by pulling EN to low. In this mode, the output voltage follows the input voltage with a voltage drop by the resistance of the inductor and high-side FET.

The TPS61256xC 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.
