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 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 applications.

The NCP1729 is available in the space saving TSOP–6 (SOT–23–6)

package.
