Product Description

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.
