♦ Requires Only Four Capacitors

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.

♦ Dual Outputs (Positive and Negative)

♦ Low Input Voltages: +1.75V to +6.0V

♦ 1µA Logic-Controlled Shutdown

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

55Ω output impedance permits useful output currents

up to 20mA. The MAX864 also has a 1µA logic-con-

trolled shutdown.

♦ Selectable Frequencies Allow Optimization

of Capacitor Size and Supply Current

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.
