Portable Instruments The LTCВ®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 …
