Detailed Description

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 uA, and a power saving shutdown input is provided to further reduce the current to a mere 0.4 uA. The device contains a 35 kHz oscillator that drives four low resistance MOSFET switches, yielding a low output resistance of 26 Ohm and a voltage conversion efficiency of 99%. This device requires only two external 3.3uF capacitors for a complete inverter making it an ideal solution for numerous battery powered and board level applications. The NCP1729 is available in the space saving TSOP−6 package.
