The TC1044S is a pin-compaTIble upgrade to the Industrystandard TC7660 charge pump voltage converter. Itconverts a +1.5V to +12V input to a corresponding –1.5Vto –12V output using only two low cost capacitors, eliminaTInginductors 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 frequencyof 10kHz. Frequency is increased to 45kHz when pin 1 isconnected to V+. OperaTIon below 10kHz (for lower supplycurrent applications) is possible by connecting an externalcapacitor from OSC to ground (with pin 1 open).The TC1044S is available in both 8-pin DIP and8-pin small outline (SOIC) packages in commercial andextended temperature ranges.
