♦ 95% Voltage-Conversion Efficiency  
♦ 85% Power-Conversion Efficiency  
♦ +2V to +6V Voltage Range  
The MAX680/MAX681 a re monolithic , CMOS, d ua l  
charge-pump voltage converters that provide ±10V out-  
puts from a +5V input voltage. The MAX680/MAX681 pro-  
vide both a positive step-up charge pump to develop  
+10V from +5V input and an inverting charge pump to  
generate the -10V output. Both parts have an on-chip,  
8kHz oscillator. The MAX681 has the capacitors internal to  
the package, and the MAX680 requires four external  
capacitors to produce both positive and negative voltages  
from a single supply.  
♦ Only Four External Capacitors Required (MAX680)  
♦ No Capacitors Required (MAX681)  
♦ 500µA Supply Current  
♦ Monolithic CMOS Design  
The output source impedances are typically 150Ω, pro-  
viding useful output currents up to 10mA. The low quies-  
cent current and high efficiency make this device suitable  
for a variety of applications that need both positive and  
negative voltages generated from a single supply.  
_______________Ord e rin g In fo rm a t io n  
The MAX864/MAX865 are also recommended for new  
designs. The MAX864 operates at up to 200kHz and uses  
smaller capacitors. The MAX865 comes in the smaller  
µMAX package.

The MAX680/MAX681 can be used wherever a single  
positive supply is available and where positive and nega-  
tive voltages are required. Common applications include  
generating ±6V from a 3V battery and generating ±10V  
from the standard +5V logic supply (for use with analog
