MM3631

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 Features （1）Input voltage range：1.8V ～ 3.3V （2）Output voltage range：− VIN （3）Operating temperature range：− 30℃～ 80℃ （4）Output current：50mA （5）consumption current (CE=L)：70 μ A (typ.) （6）Stand-by consumption current (CE=H)：1 μ A (max.) （7）Efficiency：92% (IL=1mA, VIN=2.8V) （8）Oscillation frequency 120kHz(typ.) （9）Protective function：Vin voltage protection (Except where noted otherwise : Ta=25℃ ) Package SOT-26B Applications （1）Portable devices （2）Operational Amplifier Negative Power Supply Any products men...
