Description

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 VOUT regulates to ?0.94 ? VIN and the LTC3261 draws only 60?A of quiescent current. In constant frequency mode the charge pump produces an output equal to ?VIN and 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.Applications Bipolar/Inverting Supplies Industrial/Instrumentation Bias Generators Portable Medical Equipment Portable Instruments
