Apparatus and method for controlling startup of a precharged switching regulator |
摘要 |
An apparatus for presenting a regulated output at an output locus established at a precharge level includes: (a) an error indicator generating an error signal indicating difference between a reference signal and a sensed signal; (b) a pulse indicator coupled with the error indicator generating a pulse signal indicating difference between the error signal and a periodic signal; (c) a switching device responding to the pulse signal effecting coupling of the output locus with a first terminal or a second terminal depending upon whether the pulse signal is at a first level or a second level; and (d) a driver controller coupled with the pulse indicator and the switching device that provides a control signal to the switching device indicating at least one characteristic of the pulse signal. The switching device is operative or inoperative depending upon whether the control signal is in a first state or a second state.
