The TPS6270x device is a high-efficiency synchronous step-down DC-DC converter optimized for RF power-amplifier (PA) applications. It provides up to 650 mA of output current from a single Li-Ion cell. The device converts input voltages from 2.5 to 6.0 V down to an output voltage set by an external analog reference voltage applied to the pin VCON. The output .
