An electronic device with accelerated boot process and a method for the same are proposed. When the host of the electronic device is in the off mode or standby mode, users can input a normal boot signal or a fast boot signal to activate the host. The boot signal is encoded by an encoder for producing a corresponding code. The host determines whether the input signal is the normal boot signal or the fast boot signal according to the received code. If the received code is the normal boot signal, the host performs a normal boot process. If the received code is the fast boot signal, an instant launcher directly launches application programs specified in the fast boot signal and blocks the start of unnecessary application programs. The boot process of the electronic device can be effectively accelerated, and users can define several boot modes themselves to meet different requirements.

The invention discloses a converter soft start control circuit and a control method applicable to an analog control system. A synchronous rectification Buck converter is a common bidirectional DC-DC conversion circuit topology which can realize bidirectional flow of energy. In a battery charge/discharge occasion, a relatively great start current spike is caused by adopting the traditional soft start scheme with slowly spreading duty cycle or when the inductive current in a rated steady state works in a light-load discontinuous mode after the start. In the invention, with the existing closed-loop PID regulator of a converter, the duty cycle is preset at a given duty cycle in a closed-loop manner before start. At the start moment, closed-loop start is carried out with the preset duty cycle, and great current shock is avoided while quick dynamic response of the start process can be realized to accelerate the start process. The invention can remarkably reduce the current shock in start and also is applicable to the occasions of multiple phase shedding start control of battery loads, voltage source type loads, resistive loads and converters.
