Charge Pump DC-to-DC Voltage Converter

ON Semiconductor 

MC7660

Charge Pump DC−to−DC

Voltage Converter

The MC7660 is a pin-compatible replacement for the Industry

standard ICL7660 charge pump voltage converter. It converts a +1.5 V

to +10 V input to a corresponding -1.5 V to -10 V output using only

two low-cost capacitors, eliminating inductors and their associated

cost, size and EMI.

The on-board oscillator operates at a nominal frequency of 10 kHz.

Operation below 10 kHz (for lower supply current applications) is

possible by connecting an external capacitor from OSC to ground

(with pin 1 open).

The MC7660 is available in an 8-pin SOIC package in extended

temperature range.

Features

• Converts +5.0 V Supply to -5.0 V Supply

• Wide Input Voltage Range: 1.5 V to 10 V

• Efficient Voltage Conversion: 99.9%

• Excellent Power Efficiency: 98%

• Low Power Supply: 80 µA @ 5.0 VIN

• Low Cost and Easy to Use

- Only Two External Capacitors Required

• Available in Small Outline (SO) Package

• ESD Protection: ≥ 2.5 kV

• No Dx Diode Required for High Voltage Operation

Typical Applications

• RS-232 Negative Bias

• Display Bias

• Data Acquisition Negative Supply Generation
