250-mA Adjustable (0.8V-3.3V) High-Efficiency Step-Down Charge Pump

The TPS6050x devices are a family of Step-down Charge Pumps that generate a regulated, fixed 3.3-V, 1.8-V, 1.5-V, or adjustable output voltage. Only four small ceramic capacitors are required to build a complete high efficiency DC/DC Charge Pump converter. To achieve the high efficiency over a wide input voltage range, the Charge Pump automatically selects between three different conversion modes. The output CAN deliver a maximum of 250-mA output current. The power good function supervises the output voltage and goes high when the output voltage rises to 97% of its nominal value.
