Feedback controller having multiple feedback paths |
摘要 |
A feedback controller comprises first and second feedback circuits. The first feedback circuit is connected between an input node and an output node and has an error node. The first feedback circuit comprising a feedback amplifier for comparing a feedback signal to a reference signal and providing an error signal, and a comparator for comparing the error signal to a second reference signal and providing an output signal. The second feedback circuit is connected between the input node and the error node and comprises a current source coupled to the error node and a controller coupled to the input node for controlling the current source in response to a value of the feedback signal being above or below a threshold value.
