摘要： A flyback controller generates a switching signal for controlling delivery of current into a primary winding of a transformer in a flyback converter. The controller may include an output current monitoring circuit configured to generate a signal representative of an average output current in a secondary winding of the transformer based on a peak input current in the primary winding and a duty cycle of current in the secondary winding. The flyback controller may generate a switching signal that causes a chopped AC voltage from a dimmer control to be converted by the flyback converter into an average output current from a secondary winding of the transformer that is DC isolated from the chopped AC voltage and that varies as a function of the setting of the dimmer control. The flyback controller may not utilize a signal from an opto-isolator.

摘要： A method for testing an integrated circuit to detect delay faults resulting from a signal path from a first block of the integrated circuit to a second block of the integrated circuit, wherein first and second blocks are running at different application speeds. The method may include shifting first data into scan memory cells of the integrated circuit at a first frequency; applying a launch test clock pulse to the first block at a second frequency; applying a capture test clock pulse to the second block at the second frequency, wherein the first edges of the launch and capture pulses are delayed with respect to each other by a period that is a reciprocal of the second frequency; shifting second data from the scan memory cells to an output at the first frequency; and comparing the second data at the output with expected values.
