TYPICAL APPLICATION

FEATURES

DESCRIPTION

High Voltage,

Low Quiescent Current

Inverting Charge Pump

The LTC®3261 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 60μA

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.
