DESCRIPTION
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 voltage follows the external reference by an internal gain of 2.5 within the limits of 1.3 V to 3.09 V. This scheme adjusts the output voltage of the DC/DC converter and therefore the output power of an RF-PA.
