DESCRIPTION

The SP6830/6831 devices are CMOS Charge Pump Voltage Inverters that can be imple-

mented into designs which require a negative voltage from a battery voltage source as low as

+1.15V or a power supply rail voltage as high as +5.3V. The SP6830/6831 devices are ideal

for both battery-powered and board level voltage conversion applications with a typical

operatingcurrentof70µAfortheSP6830and200µAfortheSP6831. Thesedevicescombine

an ultra-low shutdown current of <1µA with high efficiency (>95% over most of its load-current

range) which are ideal for designs using batteries such as cell phones, PDAs, medical

instruments, and other portable equipment. The SP6830/6831 devices are available in a

space-saving 6-pin SOT23-6 Package.
