www.DataSheet4U.com MAX1720 Switched Capacitor Voltage Inverter with Shutdown The MAX1720 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 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, yieldi.

MAX1719/MAX1720/MAX1721 19-1439; Rev 2; 4/04 SOT23, Switched-Capacitor Voltage Inverters with Shutdown General Description The ultra-small MAX1719/MAX1720/MAX1721 monolithic, CMOS charge-pump inverters accept input voltages ranging from +1.5V to +5.5V. The MAX1720 operates at 12kHz, and the MAX1719/MAX1721 operate at 125kHz. High efficiency, small external components, and logiccontrolled shutdown make these devices ideal for both battery-powered and board-level voltage conversion applications.

Switched Capacitor Voltage Inverter

www.DataSheet4U.com MAX1720 Switched Capacitor Voltage Inverter with Shutdown The MAX1720 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 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.
