XC6351A Series
ETR0801_003
Charge Pump Voltage Inverter IC
■ 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.

The device orientation is fixed in its embossed tape pocket. For reverse orientation, please contact your local Torex sales office or
representative. (Standard orientation: ④R-⑥, Reverse orientation: ④L-⑥)
*The dissipation pad for the USP-6B
package should be solder-plated in
recommended mount pattern and metal
masking so as to enhance mounting
strength and heat release.
If the pad needs to be connected to
other pins, it should be connected to
IN pin.
