General Description

The ultra-small MAX1682/MAX1683 monolithic, CMOS charge-pump voltage doublers accept input voltages ranging from +2.0V to +5.5V. Their high voltage-conversion efficiency (over 98%) and low operating current (110µA for MAX1682) make these devices ideal for both battery-powered and board-level voltage-doubler applications.
