MC1121 100mA Charge Pump Voltage Converter with Shutdown The MC1121 is a charge pump converter with 100mA 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 MC1121 uses no inductors saving cost, size, and reducing EMI.
An on board oscillator operates at a typical frequency of 10kHz (at VDD = 5V) when the frequency control input (FC) is connected to ground.
The oscillator frequency increases to 20
