to the charge pump, the control logic, and is compared to the user-set threshold as determined by the voltage

impedance of the CBC910 needs to be modified. The output impedance is dictated by 1/fC, where f is the

frequency of oscillation (typically 100kHz) and C is the capacitor value (typically 0.1µF). GND is system ground.
