Switched-Capacitor Voltage Doublers  
2/MAX1683  
General Description  
____________________________Features  
5-Pin SOT23 Package  
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.  
+2.0V to +5.5V Input Voltage Range  
98% Voltage-Conversion Efficiency  
110µA Quiescent Current (MAX1682)  
Requires Only Two Capacitors  
Up to 45mA Output Current  
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.
