TC1044SCPA

The TC1044SCPA is a pin-compatible upgrade to the industry standard TC7660 charge pump DC-to-DC Voltage Converter converts a +1.5 to +12V input to a corresponding -1.5 to -12V output using only two low cost capacitors, eliminating inductors and their associated cost, size and EMI. Added features include an extended supply range to 12V and a frequency boost pin for higher operating frequency, allowing the use of smaller external capacitors. The on-board oscillator operates at a nominal frequency of 10kHz. Frequency is increased to 45kHz when pin 1 is connected to V+. Operation below 10kHz (for lower supply current applications) is possible by connecting an external capacitor from OSC to ground (with pin 1 open).

• Converts +5V logic supply to ±5V system
• Efficient voltage conversion - 99.9%
• Excellent power efficiency - 98%
• Low power consumption - 80μA at VIN = 5V
• Easy to use
• Only two external capacitors required
• RS-232 Negative power supply
• Improved ESD protection up to 10kV
• No external diode required for high voltage operation
• Frequency boost raises FOSC to 45kHz
