_______________General Desc ription
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.
The internal oscillator is guaranteed to be between
20kHz and 38kHz, keeping noise above the audio
range while consuming minimal supply current. A 75
output impedance permits useful output currents up to
20mA.
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.
