Description

General part information

LTC3221 Series

The LTC3221 family are micropower charge pump DC/DC converters that produce a regulated output at up to 60mA. The input voltage range is 1.8V to 5.5V. Extremely low operating current (8μA typical at no load) and low external parts count (one flying capacitor and two small bypass capacitors at VINand VOUT) make them ideally suited for small, battery-powered applications.The LTC3221 family includes fi xed 5V and 3.3V output versions plus an adjustable version. All parts operate as Burst Mode®switched capacitor voltage doublers to achieve ultralow quiescent current. The chips use a controlled current to supply the output and will survive a continuous short-circuit from VOUTto GND. The FB pin of the adjustable LTC3221 can be used to program the desired output voltage.The LTC3221 family is available in a low profile (0.75mm) 2mm × 2mm 6-pin DFN package.ApplicationsLow Power 2 AA Cell to 3.3V SupplyMemory Backup SuppliesTire Pressure SensorsGeneral Purpose Low Power Li-Ion to 5V SupplyRF TransmittersGlucose Meters
