GENERAL DESCRIPTION
The XC6351A series are charge pump voltage inverter ICs
that have 4 MOSFETs built in. Since highly efficient negative
voltages can be generated with only 2 external capacitors
connected, GaAs bias power supplies & OpAmp's negative
power supplies etc., can be easily accommodated on a
standard PCB.
A mini-molded, 6 pin, SOT-26 and USP-6B packages provides
for space saving and makes high density mounting possible.
Low power consumption and high efficiency make this series
perfect for use with battery operated applications.
Since the IC's operations stop when output is shutdown via
the CE (chip enable) function, total power consumption
reduction is possible in applications which use this IC.
