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 +1.5V
to +10V input to a corresponding –1.5V to –10V 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 10kHz.
Operation below 10kHz (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 +5V Supply to –5V Supply
• Wide Input Voltage Range: 1.5V to 10V
• Efficient Voltage Conversion: 99.9%
• Excellent Power Efficiency: 98%
• Low Power Supply: 80µA @ 5VIN
• Low Cost and Easy to Use
– Only Two External Capacitors Required
• Available in Small Outline (SO) Package
• ESD Protection: ≥ 2.5kV
• No Dx Diode Required for High Voltage Operation
Typical Applications
• RS–232 Negative Bias
• Display Bias
• Data Aquisition Negative Supply Generation
