DESCRIPTION
The SP6832 device is a CMOS Charge Pump Voltage Inverter that can be implemented
in designs requiring a negative voltage from a positive source as low as 1.15V. The SP6832
device is ideal for both battery-powered and board level voltage conversion applications
with a typical operating current of 700mA at a 5V supply. The SP6832 can output 25mA with
a voltage drop of 500mV. These devices combine a low quiescent current with high efficiency
of 85-90% over most of its load range. Applications include cell phones, PDAs, medical
instruments and other portable equipment. The SP6832 is available in a space-saving 5-pin
SOT23 Package.
