TC682EOA Datasheet PDF - Microchip

●The TC682EOA is a charge-pump Inverting Voltage Doubler provides an inverted doubled output from a single positive supply. An on-board 12kHz (typical) oscillator provides the clock and only 3 external capacitors are required for full circuit implementation. It is a CMOS charge-pump converter with low output source impedance (typically 140W), provides output current up to 10mA. The TC682 features low quiescent current and high efficiency, making it the ideal choice for a wide variety of applications that require a negative voltage derived from a single positive supply. The minimum external parts count and small physical size of the TC682 make it useful in many medium-current, dual voltage analog power supplies.
