产品概述 返回TOP
The CXUS65175 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 CXUS65175 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 8-pin SOP Package.
