TC3682 (TC3682 - TC3684) Inverting Charge Pump Voltage Doublers

The TC3682/TC3683/TC3684 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 TC3682, 35kHz for the TC3683, and 125kHz for the TC3684. When the SHD.

• TC3682/TC3683/TC3684 General Description The TC3682/TC3683/TC3684 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 TC3682, 35kHz for the TC3683, and 125kHz for the TC3684. When the SHDN pin is held at a logic low, the device goes into a very low power mode of operation consuming less than 1µA (typ) of supply current. Low output source impedance (typically 120Ω), pro.
