General Description
The G5930 is an unregulated charge-pump voltage
inverter which may be used to generate a negative
supply from positive input. Input voltages ranging from
+1.8V to +5V can be inverted into a -1.8V to -5V out-
put supply. The devices is ideal for both battery- pow-
ered and board level voltage conversion applications
with a typical operating current of 0.45mA at 3.3V
supply.
The G5930 can deliver 25mA output current with a
voltage drop of 250mV. The parts are over -temperature
protected.
Applications include cell phones, PDAs, and other
portable equipment. The devices is available in a
space-saving 6-pin SOT-23 Package.
