发明名称 Control circuit for the current switch edges of a power transistor
摘要 A battery-charging electronic device comprises a current generator adapted to supply a charging current to a battery and a controlled current edge switch having a circuit for controlling the switching edges of current being flowed through a power transistor. The switching edge control circuit comprises a controlled edge variable voltage generator for generating a controlled edge voltage signal, a voltage/current converter for converting the voltage signal to a controlled edge current signal, and a driver circuit for the power transistor being input the controlled edge current signal to mirror, onto the power transistor, an output current which is proportional to the controlled edge current signal.
