General Description
The  G5931  is  an  unregulated  charge-pump  voltage  inverter  which  may  be  used  to  generate  a  negative  supply from positive input. Input voltages ranging from +1.8V  to  +5V  can  be  inverted  into  a  -1.8V  to  -5V  out-put supply. The devices is ideal for both battery- pow-ered  and  board  level  voltage  conversion  applications  with  a  typical  operating  current  of  0.45mA  at  3.3V  supply.      

The  G5931  can  deliver  25mA  output  current  with  a  voltage drop of 250mV. The parts are over -temperature protected.

Applications  include  cell  phones,  PDAs,  and  other  portable  equipment.  The  devices  is  available  in  8-pin  SOP Package.
