Description
General part information
TPS61259 Series
The TPS6125x device provides a power supply solution for battery-powered portable applications. Intended for low-power applications, the TPS6125x supports up to 800-mA load current from a battery discharged as low as 2.65V 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 TPS6125x 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.
