TC1044S CHARGE PUMP DC-TO-DC VOLTAGE CONVERTER

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 fo.
