8.3.2 Charge Pump Operation

These devices have an internal charge pump which turns on or off depending on the input voltage and the output current. The charge-pump switching circuitry does not cause conducted emissions to exceed required thresholds on the input-voltage line. For a given output current, the charge pump stays on at lower input voltages and turns off at higher input voltages. The charge-pump switching thresholds are hysteretic. Figure 19 and Figure 20 show typical switching thresholds for the charge pump at light (IOUT < approximately 2 mA) and heavy (IOUT > approximately 2 mA) loads, respectively.
