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.
