TC2682 - Inverting Charge Pump Voltage Doublers

Description

The TC2682/TC2683/TC2684 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.

Features

  • Small 8-Pin MSOP Package Operates from 1.8V to 5.5V 120 Ohms (typ) Output Resistance 99% Voltage Conversion Efficiency Only 3 External Capacitors Required Power-Saving Shutdown Mode Low Active Supply Current - 95μA (typ) for TC2682 - 225μA (typ) for TC2683 - 700μA (typ) for TC2684 General.
