The LTC3200/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 VIN and VOUT) 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 bith output and input ripple. The LTC3200/LTC3200-5 have thermal shutdown capability and can survive a continuous short-circuit from VOUT 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 <1µA.

The LTC3200 is available in an 8-pin MSOP package and the LTC3200-5 is available in a 6-pin SOT-23.

Product Detail

Demonstration Circuit 366A is a low noise constant frequency regulated charge pump featuring the 100mA output current LTC3200. The demo board accepts a 2.7V to 4.5V input voltage and drives six white LEDs in parallel, resulting in 16.6mA per LED. Ballast resistors are employed to provide more uniform light intensity fromr the paralleled LEDs.
