Controlling a d.c. converter by accounting for fault conditions

摘要

A controller (202) includes a fault detector (206) and a control (208). The fault detector (206) is to be coupled to a feedback circuit (121) of a power converter (100) to detect a fault condition in the power converter (100) in response to an input voltage of the power converter (102). The control (208) is coupled to the fault detector (206) and is to be coupled to control the switching of a power switch (140) to regulate an output of the power converter (100). The control (208) is coupled to inhibit the switching of the power switch (140) in response to the fault detector (206) detecting the fault condition during the switching of the power switch (140).
