Introduction

AI Translation

The TPS61256A device provides a power supply solution for battery-powered portable applications. Intended for low-power applications, the TPS61256A supports up to 800-mA load current from a battery discharged as low as 2.7V and allows the use of low cost chip inductor and capacitors. With a wide input voltage range of 2.5V to 5.5V, the device supports applications powered by Li-Ion batteries with extended voltage range and delivers a fixed 5.0V output voltage. The TPS61256A 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 36μA (typ) during light load operation. Input current in shutdown mode is less than 5μA, which maximizes battery life. 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.
