TC1044SCPA - DC DC Volt Converter DIP8

TC1044SCPA - DC/DC Adjustable Charge Pump Voltage Converter, 1.5V to 12V in, -12V to -1.5V/20 mA out, DIP-8

Descrição geral do produto
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.
