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
input is provided to further reduce the current to a mere 0.4 A. The
device contains a 35 kHz oscillator that drives four low resistance
MOSFET switches, yielding a low output resistance of 26 and a
voltage conversion efficiency of 99%. This device requires only two
external 3.3 F 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 TSOP6 package.
