_______________General Description
The MAX660 monolithic, charge-pump voltage inverter
converts a +1.5V to +5.5V input to a corresponding
-1.5V to -5.5V output. Using only two low-cost
capacitors, the charge pump’s 100mA output replaces
switching regulators, eliminating inductors and their
associated cost, size, and EMI. Greater than 90%
efficiency over most of its load-current range combined
with a typical operating current of only 120A provides
ideal performance for both battery-powered and board-
level voltage conversion applications. The MAX660 can
also double the output voltage of an input power supply
or battery, providing +9.35V at 100mA from a +5V
input.
A frequency control (FC) pin selects either 10kHz typ or
80kHz typ (40kHz min) operation to optimize capacitor
size and quiescent current. The oscillator frequency
can also be adjusted with an external capacitor or
driven with an external clock. The MAX660 is a pin-
compatible, high-current upgrade of the ICL7660.
The MAX660 is available in both 8-pin DIP and small-
outline packages in commercial, extended, and military
temperature ranges.
For 50mA applications, consider the MAX860/MAX861
pin-compatible devices (also available in ultra-small
MAX packages).
