XC6351A

XC6351A Series Charge Pump Voltage Inverter IC ETR08001-004c ■ 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, 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. ■APPLICATIONS ●Negative power supplies ●Power supplies for Opamp ●Cellular and portable phones ●Miniature LCD panels ●PDAs ●Various battery powered systems ■FEATURES Operating Voltage Range : 1.2V ~ 5.0V Oscillation Frequency : 120kHz : 35kHz (custom) Low Supply Current : 310μA (TYP.) : 100μA (35kHz custom TYP.)
