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 SP6828 and 40µA for the SP6829.
Both devices can output 25mA with a voltage drop of 500mV. These devices combine a low
quiescent current with high efficiency (>95% over most of its load-current range), which is ideal
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.
