Abstract
The invention discloses a switch power supply apparatus and a transient peak current compensation method thereof. The transient peak current compensation method includes steps of: driving a load with a rated current by the switch power supply apparatus under a stable operating state; and, driving the load with an initial peak current over the rated current within a predetermined period since the switch power supply apparatus was started up.
