  • Controlling inrush current from a power supply to a load
    Patent number: 7642677
    Abstract: Apparatus (100) for controlling inrush current from a power supply (250) to a load (255), the apparatus comprising a first (105a) and a second (105b) power supply input and a first (110a) and a second (110b) load output, a semiconductor device (115) coupled between the first power supply input (105a) and the first load output (110a), a control circuit (120) having a control circuit input (125) coupled to the first load output (110a) and a control circuit output (130) coupled to a conductance control node (135) of the semiconductor device (115), wherein, in use, when a load (255) is connected across the first load output (110a) and the second load output (110b), the control circuit (120) provides a control signal to the conductance control node (130) to thereby progressively vary the conductance of the semiconductor device (115) from a low conductance state to a high conductance state in response to a load signal being provided to the control circuit input (125) indicating that a load current (Isd) flowing thr
