Product Overview NCP1729: 50 mA, 35 kHz Switched Capacitor Voltage Inverter with Shutdown For complete documentation, see the data sheet Product 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 µA, and a power saving shutdown input is provided to further reduce the current to a mere 0.4 µA. The device contains a 35 kHz oscillator that drives four low resistance MOSFET switches, yielding a low output resistance of 26 Ω and a voltage conversion efficiency of 99%. This device requires only two external 3.3µF 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 (SOT-23-6) package.
