_________________________________________________________________________________ 5. charge pump ics 49 xc6351a series charge pump voltage inverter ic general description features the xc6351a series are charge pump voltage inverter ics that have 4 mosfets built in. since highly efficient negative volt- ages can be generated with only 2 external capacitors con- nected, gaas bias power supplies & opamp's negative powe r 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 re- duction is possible in applications which use this ic. operating voltage range: 1.2v to 5.0v oscillator frequency: 120khz 35khz ( custom ) low supply current: 310 a ( typ ) 100 a ( typ ; 35khz ) high efficiency: 90% (typ) ( rl = 2k ) stand-by current: 2.0 a (max.) ultra small package: sot-26 mini mold pin configuration pin assignment 5 6 4 2 1 3 gnd ce/ c1+ c1- v in v out sot-26 (top view) pin number symbol function 1 gnd ground 2 ce/ chip enable (-ve logic) 3 c1+ external capacitor +pin 4v out reverse output pin 5v in power supply pin 6 c1- external capacitor -pin block diagram c1+ c1- v in ce/ buffer oscillator chip enable gnd p1 n2 n4 n3 v out ordering information xc6351a ???? symbol description ?? 120 oscillation frequency 120khz 035 oscillation frequency 35khz (custom) mpackage sot-26 r embossed tape standard feed l embossed tape reverse feed
