... LTC3201 draws only leakage current (<1 A) from the V supply. Furthermore disconnected from V OUT LTC3201 is in shutdown when a logic low is applied to all three D0:D2 pins. Note that if V shutdown current will increase max. In normal operation, the quiescent supply current of the LTC3201 will be slightly higher if any of the D0:D2 pins is driven high ...

... U APPLICATIO S I FOR ATIO www.DataSheet4U.com Power Efficiency The power efficiency ( ) of the LTC3201 is similar to that of a linear regulator with an effective input voltage of twice the actual input voltage. This occurs because the input current for a voltage doubling charge pump is approxi- mately twice the output current ideal regulator the ...
