3 Description
The TPS6050x devices are a family of switched
capacitor voltage converters, designed specifically for
space-critical battery-powered applications.
The TPS6050x step-down charge pumps 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 the nominal
value.
The TPS6050x devices come in a micro-small 10-pin
VSSOP package.
