Overview
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.
Oscillator control circuitry and four power MOSFET switches are included on-chip.
A typical MAX1719/ MAX1720/MAX1721 application is generating a -5V supply from a +5V logic supply to power analog ci...
