+5V to ±10V Voltage Converters
________________General Description
The MAX680/MAX681 are monolithic, CMOS, dual
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.
The output source impedances are typically 150 ? , 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.
____________________________Features
o 95% Voltage-Conversion Efficiency
o 85% Power-Conversion Efficiency
o +2V to +6V Voltage Range
o Only Four External Capacitors Required (MAX680)
o No Capacitors Required (MAX681)
o 500μA Supply Current
o Monolithic CMOS Design
_______________Ordering Information
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.
________________________Applications
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
