MAX680EPA+

The MAX680EPA+ is a +5V to ±10V voltage converter in 8 pin DIP package. This monolithic, CMOS dual charge pump converter provides both positive step-up charge pump to develop +10V from +5V input and an inverting charge pump to generate -10V output. It has an on-chip 8KHz oscillator and requires four external capacitors to produce both positive and negative voltages from single supply. The output source impedance is typically 150 ohm, providing useful output currents up to 10mA. The low quiescent current and high efficiency make this device suitable for variety of applications that need both positive and negative voltages generated from single supply. The MAX680 can be used wherever a single positive supply is available and where positive and negative voltages are required. Common applications include generating ±6V from 3V battery, generating ±10V from standard +5V logic supply, data acquisition systems, panel meters, battery operated equipment & operational amplifier power supplies.

• Supply voltage range from 2V to 6V

• Supply current of 500μA at VCC = 3V, TA = +25°C
• Generates positive and negative doubled outputs simultaneously
• Voltage conversion efficiency of 99%
• Power conversion efficiency of 85%
