TC682 Inverting Voltage Doubler Features: General Description: 99.9% Voltage Conversion Efficiency The TC682 is a CMOS charge pump converter that provides an inverted doubled output from a single 92% Power Conversion Efficiency positive supply. An on-board 12 kHz (typical) oscillator Wide Input Voltage Range: provides the clock and only 3 external capacitors are - +2.4V to +5.5V required for full circuit implementation. Only 3 External Capacitors Required Low output source impedance (typically 140 ), 185 A Supply Current provides output current up to 10 mA. The TC682 fea- Space-Saving 8-Pin SOIC and 8-Pin PDIP tures low quiescent current and high efficiency, making Packages it the ideal choice for a wide variety of applications that require a negative voltage derived from a single Applications: positive supply (for example: generation of -6V from a 3V lithium cell or -10V generated from a +5V logic -10V from +5V Logic Supply supply). -6V from a Single 3V Lithium Cell The minimum external parts count and small physical Portable Handheld Instruments size of the TC682 make it useful in many medium- Cellular Phones current, dual voltage analog power supplies.
