SGM3209 - Charge Pump DC/DC Converter
The SGM3209 is a charge pump voltage converter which is used to generate a negative supply from a positive input.
The 3V to 18V input voltage can be converted into a corresponding -3V to -18V output supply.
The SGM3209 is also capable of delivering up to 100mA of output current.
