MAX1720
Switched Capacitor Voltage
Inverter with Shutdown
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 67 mA, and a power saving shutdown
input is provided to further reduce the current to a mere 0.4 mA. The
device contains a 12 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 10 mF capacitors for a complete inverter making it an ideal
solution for numerous battery powered and board level applications.
The MAX1720 is available in the space saving TSOP−6 package.
