19-4667; Rev 1; 7/94 Switched-Capacitor Voltage Converters _______________General Description ____________________________Features The MAX1044 and ICL7660 are monolithic, CMOS Miniature �MAX Package switched-capacitor voltage converters that invert, dou- 1.5V to 10.0V Operating Supply Voltage Range ble, divide, or multiply a positive input voltage. They are 98% Typical Power-Conversion Efficiency pin compatible with the industry-standard ICL7660 and LTC1044. Operation is guaranteed from 1.5V to 10V with Invert, Double, Divide, or Multiply Input Voltages no external diode over the full temperature range. They BOOST Pin Increases Switching Frequencies deliver 10mA with a 0.5V output drop. The MAX1044 (MAX1044) has a BOOST pin that raises the oscillator frequency above the
