The ultra-small MAX1682/MAX1683 monolithic, CMOS

charge-pump voltage doublers accept input voltages

ranging from +2.0V to +5.5V. Their high voltage-con-

version efficiency (over 98%) and low operating current

(110µA for MAX1682) make these devices ideal for

both battery-powered and board-level voltage-doubler

applications.

Oscillator control circuitry and four power MOSFET

switches are included on-chip. The MAX1682 operates

at 12kHz, and the MAX1683 operates at 35kHz. A typi-

cal application includes generating a 6V supply to

power an LCD display in a hand-held PDA. Both parts

are available in a 5-pin SOT23 package and can deliver

30mA with a typical voltage drop of 600mV.
