Inverting Charge Pump Voltage Doublers With Active High Shutdown Technology

The TC1682 TC1683 TC1684 are CMOS Charge Pump converters that provide an inverted doubled output from a single positive supply. An on-board Oscillator provides the Clock and only three external capacitors are required for full circuit implementation. Switching frequencies are 12kHz for the TC1682 35kHz for the TC1683 and 125kHz for the TC1684. When the SHDN pin is held at a Logic high, the device goes into a very low power mode of operation consuming less than 1A (typ) of supply current. Low output source impedance (typically 120), provides output current up to 10mA. The TC1682 TC1683 TC1684 feature a 1.8V to 5.5V operating voltage range and high efficiency, which make them an ideal choice for a wide variety of applications requiring a negative doubled voltage derived from a single positive supply (for example: generation of -7.2V from a +3.6V lithium cell or -10V generated from a +5V Logic supply). The minimum external part count, small physical size and shutdown mode feature make this family of products useful for a wide variety of negative bias power supply applications.
