Description

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
ESD sensitive device, take proper precaution while handling the device.
