Low Power Consumption ...........80uA @ VIN = 5V
Low Cost and Easy to Use
Only Two External Capacitors Required
RS-232 Negative Power Supply
Available in 8-Pin Small Outline (SOIC) and 8-Pin Plastic DIP Packages
Improved ESD Protection .............Up to 10kV
No External Diode Required for High Voltage Operation
Frequency Boost Raises FOSC to 45kHz
Description
The TC1044S is a pin-compatible upgrade to the Industry standard TC7660 charge pump voltage converter. It converts a +1.5V to +12V input to a corresponding –1.5V 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. Theon-boardoscillatoroperates atanominalfrequency 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). The TC1044S is available in both 8-pin DIP and 8-pin small outline (SOIC) packages in commercial and extended temperature ranges.
