ABSTRACT:
An in-rush current limiting circuit is disclosed. An apparatus according to aspects of the present invention includes a power switch having a first, second and third terminals. A capacitor having a first terminal and a second terminal is also included. The second terminal of the capacitor is coupled to the first terminal of a current source. The second terminal of the current source is coupled to a second input terminal of the in-rush current limit circuit. A power switch is also included. The first terminal of the power switch is coupled to the anode of a diode. The cathode of the diode is connected to the first terminal of the current source. The second terminal of the power switch is coupled to a second input terminal of the in-rush current limit circuit. The third terminal of the power switch is coupled to be responsive to a voltage across the current source circuit in response to a rate of change of voltage between first and second terminals of the power switch.
