L6668 General Description

L6668 is a current-mode primary controller IC, designed to build single-ended converters. The IC drives the system at fixed frequency at heavy load and an improved Standby function causes a smooth frequency reduction as the load is progressively reduced. At very light load the device enters a speci.
