*Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or other conditions above those indicated in the operation section of the specification is not implied. Exposure to the Absolute Maximum Ratings conditions for extended periods of time may affect device reliability.

The TCM680 is a dual charge pump voltage converter that develops output voltages of +2V_IN and 2V_IN from a single input voltage of +2.0V to +5.5V. Common applications include ±10V from a single +5V logic supply, and ±6V from a +3V lithium battery.

The TCM680 is packaged in a space-saving 8-pin SOIC package and requires only four inexpensive external capacitors. The charge pumps are clocked by an on-board 8kHz oscillator. Low output source impedances (typically 150W) provides maximum output currents of 10mA for each output. Typical power conversion efficiency is 85%.

High efficiency, small installed size and low cost make the TCM680 suitable for a wide variety of applications that need both positive and negative power supplies derived from a single input voltage.
