ABSTRACT:
Compensation for a switching regulator is attained by developing a compensation signal for a switching regulator that is independent of changes in the switching frequency. The regulator operational frequency is established in accordance with a repetitive ramp signal of constant slope and adjustable frequency. The voltage of the ramp signal is monitored and an offset signal is derived therefrom. The peak value of the ramp signal, detected during monitoring, is used to derive the offset signal. Initiation of the compensation occurs at the same duty cycle point during each switching cycle and thus is independent of switching frequency. The compensation signal may have a linear or non-linear slope.
