    摘要： A selector circuit configured to select among a DC power source and a plurality of batteries for an electronic device. The selector circuit includes a first comparator configured to compare a first input signal representative of a voltage level of the DC power source with a first threshold level and provide a first output signal representative of a difference between the first input signal and the first threshold level, and a selector output circuit. The selector output circuit is configured to provide selector output signals that control selection among the DC power source and the plurality of batteries. The selector output circuit providing said selector output signals to select the DC source and deselect the plurality of batteries if the first output signal is representative of the voltage level of said DC power source being greater than the first threshold level.

    摘要： An enabling circuit includes a comparison circuit configured to compare a feedback signal representative of a charge of an energy storage element of a regulating circuit with a reference charge and provide an output in response to the comparison to enable the regulating circuit to switch from a first state to a second state if the charge of the energy storage element is less than the reference charge. The enabling circuit may also be used to enable a synchronous rectifier converter to provide a charging current to a battery in a battery charging system of an electronic device thereby avoiding negative voltage transients that may otherwise occur at the output of the synchronous rectifier converter. Various methods are also provided.
