The LTC
3204-3.3/LTC3204-5/LTC3204B-3.3/LTC3204B-5
are low noise, constant frequency (1.2MHz) switched ca-
pacitor voltage doublers. The LTC3204-3.3/LTC3204B-3.3
can produce a regulated output voltage of 3.3V
from a minimum input voltage of 1.8V (2 alkaline cells)
whereas the LTC3204-5/LTC3204B-5 can produce 5V from
a minimum of 2.7V (Li-Ion battery) input.
LTC3204-3.3/LTC3204-5 feature automatic Burst Mode
operation at light loads to maintain low supply current
whereas LTC3204B-3.3/LTC3204B-5 feature constant
frequency operation at any load. Built-in soft-start circuitry
prevents excessive inrush current during start-up. Thermal
shutdown and current-limit circuitry allow the parts to
survive a continuous short-circuit from V
OUT
to GND.
High switching frequency minimizes overall solution
footprint by allowing the use of tiny ceramic capaci-
tors. In shutdown, the load is disconnected from the
input and the quiescent current is reduced to <1μA. The
LTC3204-3.3/LTC3204-5/LTC3204B-3.3/LTC3204B-5 are
available in a low profile (0.75mm) 6-lead 2mm × 2mm
DFN package.
