• description

  The LTC^®3200/LTC3200-5 are low noise, constant frequency switched capacitor voltage doublers. ^{LTC®3200/LTC3200-5}is a low noise, constant frequency switched capacitor voltage multiplier. They produce a regulated output voltage from a 2.7V to 4.5V input with up to 100mA of output current.They generate 100mA of output current, regulating the output voltage from 2.7V to 4.5V with input maximum. Low external parts count (one flying capacitor and two small bypass capacitors at V_INand V_OUT) make the LTC3200/LTC3200-5 ideally suited for small, battery-powered applications.Low external component count (one float capacitor and two small bypass capacitors at V.)_INand V_OUTThis 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.A new charge pump architecture maintains a 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_OUTto GND.The LTC3200/LTC3200-5 have a thermal shutdown capability that can be switched from V_OUTSurvive continuous short circuit to GND. Built-in soft-start circuitry prevents excessive inrush curreent during start-up.Built-in soft-start circuitry prevents excessive surge curreent during start-up.

  High switching frequency enables the use of small ceramic capacitors.The high switching frequency allows the use of small ceramicscapacitor。 A low current shutdown feature disconnects the load from VIN and reduces quiescent current to A low-current shutdown function disconnects the load from VIN and reduces quiescent current

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