Claim Text:
1. A method comprising: driving a base current from a base current source to a base of a bipolar junction transistor (BJT) to maintain conduction of the bipolar junction transistor (BJT) during a first time period; disconnecting the base current source from the bipolar junction transistor (BJT) during a second time period; receiving a current measurement from a current detect circuit coupled to an emitter of the bipolar junction transistor (BJT); repeating the steps of driving the base current during the first time period and disconnecting the base current source for the second time period to obtain an average current output to a load; and dynamically adjusting the base current output from the base current source to adjust a reverse recovery time period of the bipolar junction transistor (BJT) based, at least in part, on the received current measurement.
