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 VOUT to 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 profi le (0.75mm) 2mm × 2mm 6-pin DFN package.
