Device Overview

Summary

The TC682 is a CMOS charge pump converter that 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.Low output source impedance (typically 140Ohms), 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 (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.

8-Pin SOIC/MSOP/TSSOP/DIP Evaluation Board ( SOIC8EV )

This is a blank PCB that allows the operation of Microchip Technology’s 8-pin devices to be easily evaluated. Each device pin is connected to a pull-up resistor, a pull-down resistor, an in-line resistor, and a loading capacitor. The PCB pads allow through hole or surface mount connectors to be installed to ease connection to the board. Additional passive component footprints are on the...
