Abstract

See full text

A soft-start device including a current source, a first transistor, and a second transistor is described. The first transistor is coupled to the current source, and an amount of current conducted by the first transistor is determined according to a voltage. The second transistor is also coupled to the current source, and an amount of current conducted by the second transistor is determined according to a fixed bias. An initial voltage value of the voltage is smaller than a voltage value of the fixed bias. However, after a soft start, the voltage value of the first voltage is increased gradually to be larger than the voltage value of the fixed bias, such that the soft start may be implemented smoothly.
