LTC3200

The LTC^®3200/LTC3200-5 are low noise, constant frequency switched capacitor voltage doublers. They produce 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 capacitors 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 shortcircuit 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 <1A.

The LTC3200 is available in an 8-pin MSOP package and the LTC3200-5 is available in a 6-pin ThinSOT.
