_______________General Desc ription
The MAX864 CMOS, charge-pump, DC-DC voltage
converter produces a positive and a negative output
from a single positive input, and requires only four
capacitors. The charge pump first doubles the input
voltage, then inverts the doubled voltage. The input
voltage ranges from +1.75V to +6.0V.
The internal oscillator can be pin-programmed from
7kHz to 185kHz, allowing the quiescent current, capac-
itor size, and switching frequency to be optimized. The
55
output impedance permits useful output currents
up to 20mA. The MAX864 also has a 1μA logic-con-
trolled shutdown.
The MAX864 comes in a 16-pin QSOP package that
uses the same board area as a standard 8-pin SOIC.
For more space-sensitive applications, the MAX865 is
available in an 8-pin μMAX package, which uses half
the board area of the MAX864.
