TC682EOA Inverting Voltage Doubler

General Description:
The TC682 is a CMOS charge pump converter that provides an inverted doubled output from a single positive supply. An on-board 12 kHz (typical) oscillator provides the clock and only 3 external capacitors are required for full circuit implementation.
Low output source impedance (typically 140Ω), provides output current up to 10 mA. 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 (for example: generation of -6V from a 3V lithium cell or -10V generated from a +5V logic 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.

Features:
• 99.9% Voltage Conversion Efficiency
• 92% Power Conversion Efficiency
• Wide Input Voltage Range:
   - +2.4V to +5.5V
• Only 3 External Capacitors Required
• 185 μA Supply Current
• Space-Saving 8-Pin SOIC and 8-Pin PDIP Packages

Applications:
• -10V from +5V Logic Supply
• -6V from a Single 3V Lithium Cell
• Portable Handheld Instruments
• Cellular Phones
• LCD Display Bias Generator
• Panel Meters
• Operational Amplifier Power Supplies
