Asynchronous clock pulse generation in DC-to-DC converters

Abstract:

Generally speaking, a pulse generation unit can aid load transient response for a DC-to-DC converter. In some examples, a pulse generation unit is coupled to an output voltage of the DC-to-DC converter. The pulse generation unit includes a transient sensing unit and a clock augmentation unit. The transient sensing unit monitors the output of the DC-to-DC converter. When the transient sensing unit detects a load transient, the transient sensing unit generates an additional clock pulse. The clock augmentation unit augments an existing clock signal to include the additional clock pulse.
