Abstract
A charger having a fast transient response and a control method thereof are provided, which decide how to quickly respond to a requirement of a load by determining whether an input current reference signal indicating an input current is larger than or equal to a maximum safe current of a transformer. Therefore, the charger and the control method realize the fast transient response without having to control switching between a boost circuit and a buck circuit. Meanwhile, the charger and the control method thereof can be prevented from being damaged by an excessive input current and can stabilize an output voltage of the load more quickly.
