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.
