[Outline]
MM3631XN is an unregulated charge pump voltage converter, convert a input voltage range of 1.8V to 3.3V into a negative voltage. MM3631XN uses two low cost capacitors.
The device is small packaged in a 6-pin SOT-26B CE circuit included.
Stand-by current is less than 1µA, reduce the quiecent current.
