Abstract
An overcurrent protection circuit includes a hiccup controller which is configured to hiccup-drive a switching element such that an on-period and an off-period alternate. The hiccup controller controls at least one of the on- and off-period according to a temperature sense signal. The temperature sense signal can be generated by detecting at least one of temperature of the switching element and a difference in temperature between the switching element and another element. When at least one of temperature of the switching element and the difference in temperature between the switching element and the other element is higher than a predetermined threshold value, the hiccup controller can reduce the on-period ton and increase the off-period.
