Description
The KA7511 drives, regulates and monitors the main switch-
ing element in a SMPS based on the nonsynchronous flyback
theory. Because of the wide regulating range and the high
voltage stability during large load changes, the power sup-
plies for TV receivers and video recorders can be realized.
