Product Overview

The TC1044SEOA is a charge pump DC-to-DC Voltage Converter. It 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).
  • 99.9% Efficient voltage conversion
  • 98% Excellent power efficiency
  • Easy to use
  • RS-232 negative power supply
  • Up to 10kV improved ESD protection
  • No external diode required for high voltage operation
  • Frequency boost raises FOSC to 45kHz
