Low Power Voltage Inverters With Shutdown
SP6830/6831
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
operating current of 70
μ
A for the SP6830
and 200
μ
A for the SP6831. These devices
combine
an ultra-low shutdown current of <1
μ
A 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.
