MAX864 - Dual-Output Charge Pump with Shutdown

Download the MAX864 datasheet PDF. This datasheet also covers the MAX variant, as both devices belong to the same dual-output charge pump with shutdown family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • o Requires Only Four Capacitors o Dual Outputs (Positive and Negative) o Low Input Voltages: +1.75V to +6.0V o 1µA Logic-Controlled Shutdown o Selectable Frequencies Allow Optimization of Capacitor Size and Supply Current MAX864 ______________Ordering Information PART MAX864C/D MAX864EEE TEMP.

19-0478; Rev 0; 3/96 Dual-Output Charge Pump with Shutdown _______________General Description 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, capacitor 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-controlled shutdown. The MAX864 comes in a 16-pin QSOP package that uses the same board area as a standard 8-pin SOIC.
