10 pcs : TPS61253YFFR - Switching Voltage Regulators 3.5MHz Hi Eff Step- Up Converter

TPS6125x High Efficiency Step-Up Converters Texas Instruments TPS6125x High-Efficiency Step-Up Converters provide a power supply solution for battery-powered portable applications. Intended for low-power applications, the TPS6125x supports up to 800mA load current from a battery discharged as low as 2.65V and allows the use of low-cost chip inductors and capacitors. With a wide input voltage range of 2.3V to 5.5V, the device supports applications powered by Li-Ion batteries with an extended voltage range. Different fixed voltage output versions are available from 3.15V to 5.0V. The Texas Instruments TPS6125x operates at a regulated 3.5MHz 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 37µA (typ.) during a light load operation.
