Charge pump voltage converter IC MM3631
Charge pump voltage converter IC Monolithic IC MM3631
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 1 μ A, reduce the quiecent current
