FEATURES  
DESCRIPTIO  
TheLTC®3221familyaremicropowerchargepumpDC/DC  
converters that produce a regulated output at up to 60mA.  
The input voltage range is 1.8V to 5.5V. Extremely low  
operating current (8µA typical at no load) and low external  
parts count (one flying capacitor and two small bypass

small, battery-powered applications.  
■
Very Low Shutdown Current: <1µA  
The LTC3221 family includes fixed 5V and 3.3V output  
versions plus an adjustable version. All parts operate  
as Burst Mode® switched capacitor voltage doublers  
to achieve ultralow quiescent current. The chips use a  
controlled current to supply the output and will survive
