The TC1044SCPA is a DC-to-DC charge-pump 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 its associated 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. It is pin-compatible upgrade to the Industry standard TC7660 charge-pump voltage converter. 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.
- Easy to use - Only two external capacitors required
- No external diode required for high voltage operation
- RS-232 Negative power supply
- Converts 5V logic supply to ±5V system
- 99.9% Efficient voltage conversion
- 98% Excellent power efficiency
- 80µA at VIN = 5V Low power consumption
- Up to 10kV improved ESD protection
- No external diode required for high voltage operation
- Frequency boost raises FOSC to 45kHz

Do not exceed maximum supply voltages. Do not short circuit the output to V+ supply for voltages above 5.5V for extended periods, however, transient conditions including start-up are okay.
