2mm 6-Pin DFN Package
The LTC
®
3221 family are micropower charge pump DC/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
capacitors at V
IN
and V
OUT
) make them ideally suited for
small, battery-powered applications.
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
a continuous short-circuit from V
OUT
to GND. The FB pin
of the adjustable LTC3221 can be used to program the
desired output voltage.
The LTC3221 family is available in a low profile (0.75mm)
