The CXUS65174 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 output supply. The devices is ideal for both battery- powered and board level voltage conversion applications with a typical operating current of 0.45mA at 3.3V supply. The CXUS65174 can deliver 60mA output current with a voltage drop of 580mV. 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 and TDFN2X2 6-pin Package.
