The LTC ? 3200/LTC3200-5 are low noise, constant fre-
quency switched capacitor voltage doublers. They pro-
duce a regulated output voltage from a 2.7V to 4.5V input
with up to 100mA of output current. Low external parts
count (one flying capacitor and two small bypass capaci-
tors at V IN and V OUT ) make the LTC3200/LTC3200-5
ideally suited for small, battery-powered applications.
A new charge-pump architecture maintains constant
switching frequency to zero load and reduces both output
and input ripple. The LTC3200/LTC3200-5 have thermal
shutdown capability and can survive a continuous short-

circuit from V OUT to GND. Built-in soft-start circuitry
prevents excessive inrush current during start-up.
High switching frequency enables the use of small ceramic
capacitors. A low current shutdown feature disconnects
the load from V IN and reduces quiescent current to <1 μ A.
