Abstract
An inrush current suppressing circuit connected between a power supply and a working circuit of an electronic device includes a first power supply circuit and a second power supply circuit both connected between the power supply and the working circuit. The first power supply circuit suppresses inrush current and forwards power from the power supply to the working circuit when the electronic device is powered on. The second power supply circuit forwards power from the power supply to the working circuit when the power supply reaches a predetermined voltage.
