Circuit and method for reducing output voltage transients in a voltage mode buck converter
Abstract:
A voltage control mode buck converter circuit includes a feedback amplifier providing a comparison signal and a storage circuit in communication with the comparison signal to store a storage comparison signal value. The storage circuit stores the operating conditions for the circuit during normal continuous conduction mode operation in response to sensing a load drop for the circuit. A switching circuit locks the feedback amplifier into the stored operating parameters while the converter circuit operates in non-continuous conduction mode. When the circuit transitions back into the continuous conduction operation mode, the feedback amplifier is already operating at conditions that are compatible with a continuous conduction operation mode.
