Product Summary
The FAN6754MR is a highly integrated controller that provides several features to enhance the performance of flyback converters. To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to continuously decrease the switching frequency under light-load conditions. The applications of the FAN6754MR are General-purpose switch-mode power supplies and flyback power converters.
