General Description
TCM680 General Description
The TCM680 is a dual charge pump voltage converter that develops output voltages of +2VIN and 2VIN 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.
