Patent ID: 7809408

Claim:
A method for electronic power supply control, the method comprising: selecting a resistance of at least one resistive component, which is coupled between an input control signal and an output stage circuit of a power switch circuit, wherein said power switch circuit comprises a plurality of buffers coupled between said input control signal and said output stage circuit, so as to limit a peak transient current level, said peak transient current level results from in-rush current delivered by said power switch circuit to a load impedance circuit during a transient time interval during which a voltage level across said load impedance circuit rises or falls from an initial voltage level to a quiescent voltage level; and limiting a rate of change of said voltage level across said load impedance circuit during said rise or fall from said initial voltage level to said quiescent voltage level, wherein said limiting of said rate of change of said voltage level across said load impedance limits said peak transient current level, wherein said change in voltage is caused by a change in voltage generated by at least one of said plurality of buffers.
