DESCRIPTION

The SP6828/6829 devices are CMOS Charge Pump Voltage Inverters that can be

implemented in designs requiring a negative voltage from a +3V battery source. The SP6828/

6829 devices are ideal for both battery-powered and board level voltage conversion

applications with a typical operating current of 20µA for the SP6828and 40µA for theSP6829.

Both devices can output 25mA with a voltage drop of 500mV. These devices combine a low

quiescentcurrentwithhighefficiency(>95%overmostofitsload-currentrange),whichisideal

for designs using +3.3V or +3.6V lithium ion batteries. Applications include cell phones,PDAs,

medical instruments and other portable equipment. The SP6828/6829 devices are available in

a space-saving 5-pin SOT23 Package.
