ABSTRACT:
A power converter circuit, which is voltage-regulated and current-limited by a peak current control circuit, significantly reduces the current tailout effect by decreasing the frequency of operation of the converter during low voltage output current-limited operation by increasing the nonconduction interval of the power switch while maintaining a fixed conduction interval.
The peak current control circuit periodically initiates current conduction in the power switch in response to a clock pulse, and terminates conduction when a peak current level is attained. The peak current control includes circuitry to compare decaying current in the filter circuit during nonconducting intervals with a preset current tailout threshold level. The periodic triggering of the power switch into conduction is inhibited until current has decayed to this current tailout threshold level.
