XC6351A
Series
Charge Pump Voltage Inverter IC
ETR0801_001
■
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.
