Product Summary
The SG5841DZ is a PWM controller which provides several features to enhance the performance of flyback converters. It provides many protection functions. In addition to cycle-by-cycle current limiting, the internal open-loop protection circuit ensures safety should an open-loop or output-short-circuit failure occur. The device is available in an 8-pin DIP or SOP package. The applications of the SG5841DZ include: Power adapters, open-frame SMPS.
