Inverting Voltage Doubler Consumes Little Power

The SP682 ultra-low-power inverting voltage doubler is a monolithic charge-pump voltage converter that produces a doubled, negative voltage from a single positive supply. Three external charge-pump capacitors are required to support the voltage conversion and voltage-doubling process.Operating from a +2.4V to +5.5V input range, the chip converts a +5V input to a -10V output. The device is said to consume about one-third the power of competitive devices and offers 99% voltage conversion efficiency. It operates from 60 µA of supply current and consumes just 1 µA in shutdown mode.The charge pump is suited for low-power applications requiring a typical +3V battery source such as a lithium cell. Uses include portable computers and cellular phones.
