Product Summary

The ultra-small MAX870EUKABZN monolithic, CMOS charge-pump inverter accepts input voltages ranging from +1.4V to +5.5V. The MAX870EUKABZN operates at 500kHz. It is high efficiency (90%) and low operating current (0.7mA for the MAX870) make these devices ideal for both battery-powered and board-level voltage-conversion applications. A typical MAX870EUKABZN application is generating a -5V supply from a +5V logic supply to power analog circuitry.
