RoHS: Compliant
View Datasheet Manufacturer Site View Pricing & Stock

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.
