Overview
- 1.11mm-High µMAX Package
- Compact: Circuit Fits in 0.08in²
- Requires Only Four Capacitors
- Dual Outputs (positive and negative)
- +1.5V to +6.0V Input Voltage
- 20kHz (min) Frequency (above the audio range)
The MAX865 is a CMOS charge-pump DC-DC converter 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 voltage. 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 75Ω 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 standard 8-pin SOIC. For a device with selectable frequencies and logic-controlled shutdown, refer to the MAX864 data sheet.
