With a wide input voltage range of 2.3 V to 5.5 V, the TPS6125xA supports applications powered by Li-Ion batteries with extended voltage range. This device operates at a regulated 3.5-MHz switching frequency. The TPS6125xA can be flexibly configured in the force PWM mode or the PFM mode. The PFM mode extends the battery life with high efficiency at light load while the force PWM mode is good for noise sensitive applications. TPS6125xA also provides the option of an ultrasonic mode which enables low acoustic noise at light load conditions. During shutdown, the load is completely disconnected from the battery.
