MAX871EUK+T

Price range: $1.46

The ultra-small MAX870/MAX871 monolithic, CMOScharge-pump inverters accept input voltages rangingfrom +1.4V to +5.5V. The MAX870 operates at 125kHz,and the MAX871 operates at 500kHz. Their high efficiency(90%) and low operating current (0.7mA for theMAX870) make these devices ideal for both battery-poweredand board-level voltage-conversion applications.Oscillator control circuitry and four power MOSFETswitches are included on-chip. A typical MAX870/MAX871 application is generating a -5V supply from a+5V logic supply to power analog circuitry. Both partscome in a 5-pin SOT23-5 package and can deliver 25mAwith a voltage drop of 500mV.For a similar device with logic-controlled shutdown,refer to the MAX1720/MAX1721. For applicationsrequiring more power, the MAX860 delivers up to 50mAwith a voltage drop of 600mV, in a space-saving µMAXpackage.ApplicationsBattery-Operated EquipmentCell PhonesHandy-Terminals, PDAsLocal -5V Supply from 5V Logic SupplyMedical InstrumentsSmall LCD Panels
