TC1121 100mA Charge Pump Voltage Converter

The TC1121 is a charge pump converter with 100 mA output current capability. It converts a 2.4V to 5.5V input to a corresponding negative output voltage. As with all charge pump converters, the TC1121 uses no inductors saving cost, size and EMI. An on-board oscillator operates at a typical frequenc.
