♦ 1.11mm-High µMAX Package

♦ Compact: Circuit Fits in 0.08in²

The MAX865 is a CMOS charge-pump DC-DC convert-

er in an ultra-small µMAX package. It produces positive

and negative outputs from a single positive input, and

requires only four capacitors. The charge pump first

doubles the input voltage, then inverts the doubled volt-

age. The input voltage ranges from +1.5V to +6.0V.

♦ Requires Only Four Capacitors

♦ Dual Outputs (positive and negative)

♦ +1.5V to +6.0V Input Voltage

The internal oscillator is guaranteed to be between

20kHz a nd 38kHz, ke e p ing nois e a b ove the a ud io

range while consuming minimal supply current. A 75Ω

output impedance permits useful output currents up to

20mA.

♦ 20kHz (min) Frequency (above the audio range)

The MAX865 comes in a 1.11mm-high, 8-pin µMAX

package that occupies half the board area of a stan-

dard 8-pin SOIC. For a device with selectable frequen-

cies and logic-controlled shutdown, refer to the MAX864

data sheet.
