TCM680

+5V To ±10V Voltage Converter

Features

General Description

• 99% Voltage Conversion Efficiency

• 85% Power Conversion Efficiency

• Input Voltage Range:

The TCM680 is a dual charge pump, voltage converter

that produces output voltages of +2V_INand -2V_INfrom

a single input voltage of +2.0V to +5.5V. Common

applications include ±10V from a single +5V logic

supply and ±6V from a +3V lithium battery.

- +2.0V to +5.5V

• Only 4 External Capacitors Required

• 8-Pin SOIC Package

The TCM680 is packaged in 8-pin SOIC and PDIP

packages and requires only four inexpensive, external

capacitors. The charge pumps are clocked by an on-

board 8 kHz oscillator. Low output source impedances

(typically 140 Ω) provide maximum output currents of

10 mA for each output. Typical power conversion effi-

ciency is 85%.

Applications

• ±10V From +5V Logic Supply

• ±6V From a 3V Lithium Cell

• Handheld Instruments

High efficiency, small size and low cost make the

TCM680 suitable for a wide variety of applications that

need both positive and negative power supplies

derived from a single input voltage.

• Portable Cellular Phones

• LCD Display Bias Generator

• Panel Meters

• Operational Amplifier Power Supplies
