描述
The LTC ® 3200/LTC3200-5 are low noise, constant frequency switched capacitor voltage doublers. The LTC®3200/LTC3200-5 is a low-noise, constant-frequency switching capacitive voltage multiplier. 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. The low external component count (one floating capacitor and two small bypass capacitors in V IN and V OUT) makes the LTC3200/LTC3200-5 ideal for small, battery-powered applications.

A new charge-pump architecture maintains constant switching frequency to zero load and reduces bith output and input ripple. The LTC3200/LTC3200-5 have thermal shutdown capability and can survive a continuous short-circuit from V OUT to GND. The LTC3200/LTC3200-5 has a thermal shutdown function that can continuously short circuit from V OUT to GND. Built-in soft-start circuitry prevents excessive inrush curreent during start-up.

High switching frequency enables the use of small ceramic capacitors. A low current shutdown feature disconnects the load from VIN and reduces quiescent current to 低电流关断功能，从VIN断开负载，并降低静态电流

The LTC3200 is available in an 8-pin MSOP package and the LTC3200-5 is available in a 6-pin SOT-2 LTC3200 LTC3200 3.
