Abstract
A frequency lock loop for a constant switching frequency of DC-DC converter, wherein the frequency lock loop includes a modulation circuit to generate a modulation signal in response to an input signal of the DC-DC converter and a frequency signal. Wherein a timer of the DC-DC converter generates a timing signal in response to the input signal, and wherein the frequency signal is a function of the timing signal.
