Abstract:
A standby circuit is provides to on/off a power converter for power saving. The standby circuit includes a comparison circuit. The comparison circuit is coupled to a feedback loop of the power converter to generate a mode signal when a feedback signal of the feedback loop is lower than a threshold signal. A resistive device is coupled to the feedback loop. The resistance of the resistive device is increased in response to the mode signal. The mode signal is further coupled to turn off a switching control circuit of the power converter.
