Abstract
A power supply detects a falling rate of an output voltage for fast load-transient response. The power supply with a primary side and a secondary side isolated from each other comprises a primary-side control circuit and a secondary-side control circuit. The primary-side control circuit controls a power switch to convert an input power source on the primary side into an output power source on the secondary side. The output power source has the output voltage. The secondary-side control circuit detects the falling rate and sending information to the primary-side control circuit when the falling rate exceeds a predetermined rate. In response to the information, the primary-side control circuit starts anew switching cycle of the power switch.
