Overview
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.
5 V to 5.
5 V with an output current capability in excess of 50 mA.
The operating current consumption is only 122 mA, and a power saving shutdown input is provided to further reduce the current to a mere 0.
4 mA.
The device contains a 35 kHz oscillator that drives four low resistance MOSFET switches, yielding a low output resistance of 26 W and a voltage conversion efficiency of 99%.
This device requires only two external 3.
3 mF capacitors for a complete inverter making it an ideal solution for numerous battery powered and board level a...
