Patent ID: 8587274

Claim:
A current mode power conversion system constructed to provide a stable output voltage and a maximum-limited output current to a load, the system comprising: a linear feedback control configured and arranged so as to control the output current of the current mode power conversion system and operable in a linear mode so as to provide a linear response with a controllable clock duration when controlling the output current during constant load conditions, wherein the linear feedback control includes a non-linear control configured to operate the linear feedback control in a non-linear mode only during load transient conditions above a predetermined threshold by shortening the control duration by speeding up the linear feedback control during changes in load conditions above the predetermined threshold so as to control the output current and speed up the transient response of the power conversion system during such changes so as to avoid clock latency when returning to linear operation; wherein the linear feedback control is configured and arranged to that the sensitivity of the non-linear control to load transient conditions is adjustable, and where the linear feedback control includes a discriminator configured and arranged to set high and low threshold limits, wherein the sensitivity of the non-near control to load transient conditions is a function of the level of the high and low threshold limits.
