Abstract
A controller for a power supply device includes a transmission terminal, first and second memory circuits, a determining circuit, and a control circuit. The determining circuit generates a first mode signal when an input voltage value is lower than a reference voltage value and generates a second mode signal when the input voltage value is greater than or equal to the reference voltage value. The control circuit enters a first mode and a second mode in response to the first mode signal and the second mode signal, respectively. The control circuit writes a control parameter from the transmission terminal into the first memory circuit in the first mode and uses the control parameter in the second mode to test the power supply device. When the control parameter meets an expected function of the power supply device, the control circuit writes the control parameter into the second memory circuit.
