● _________________________________________________________________________________ XC6351A Series Charge Pump Voltage Inverter IC General Description 5. Charge Pump ICs DETAILS Features 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 accomodated on a standard PCB. A mini-molded, 6 pin, SOT-26 package 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. Pin Configuration Operating Voltage Range: 1.2V to 5.0V Oscillator Frequency: 120kHz 35kHz ( custom ) Low Supply Current: 310µA ( typ ) 100µA ( typ ; 35kHz ) High Efficiency: 90% (typ) ( RL = 2kΩ ) Stand-by Current: 2.0µA (max.)
