Datasheet NCP1729 (ON Semiconductor)

NCP1729 Switched Capacitor Voltage Inverter The NCP1729 is a CMOS charge pump voltage inverter that is designed for operation over an input voltage range of 1.15 V to 5.5 V with an output current capability in excess of 50 mA. The operating current consumption is only 122 A, and a power saving shutdown
