摘要： The present application relates to a power supply module which is operable in a switch mode and in a linear mode. The power supply module includes a detector for detecting the presence of an inductor at an output node of the power supply module If an inductor is detected, the detector outputs a signal indicating the presence of the inductor, and the power supply module selects the switch mode as its operating mode. If no inductor is detected, the detector outputs a signal indicative of the absence of an inductor and the power supply module selects its linear mode as its operating mode.

摘要： In the field of battery charging for electronic devices, it is known to employ a number of measures to avoid excessive power dissipation by a pass device in a charging system. However, many of these measures are either incompatible with linear charging regimes or add cost to the adapter and/or charging system. The present invention provides a power dissipation measurement circuit for controlling a control device that acts in series with another, but maximum current limiting, control device to control drive current to the pass device so as to limit the power dissipated by the pass device to a maximum threshold value.
