Description
General part information
LTC3261 Series
The LTC3261 is a high voltage inverting charge pump that operates over a wide 4.5V to 32V input range and is capable of delivering up to 100mA of output current.The charge pump employs either low quiescent current Burst Mode operation or low noise constant frequency mode. In Burst Mode operation the charge pump VOUTregulates to –0.94 • VINand the LTC3261 draws only 60μA of quiescent current. In constant frequency mode the charge pump produces an output equal to –VINand operates at a fixed 500kHz or to a programmed frequency between 50kHz to 500kHz using an external resistor. The LTC3261 is available in a thermally enhanced 12-pin MSOP package.ApplicationsBipolar/Inverting SuppliesIndustrial/Instrumentation Bias GeneratorsPortable Medical EquipmentPortable Instruments
