Power switch with inrush current control. |
摘要 |
<p>A power control circuit is provided for coupling a load to a power source. It includes a transistor for coupling said load to the power supply through the transistor dependent upon a control voltage applied to a control terminal of the transistor, a charge pump circuit having its output connected to the transistor control terminal to apply a controlled turn on signal to the transistor when the charge pump is activated, wherein the controlled signal gradually increases until the transistor is biased into its fully on state. <IMAGE></p> |
