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.
Oscillator control circuitry and four power MOSFET switches are included on-chip. The MAX1682 operates
at 12kHz, and the MAX1683 operates at 35kHz. A typical 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.
Applications:
Small LCD Panels
Cell Phones
Handy-Terminals
PDAs
