DESCRIPTION  
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.
