onsemi FAN6240M6X 200 kHz 6-Pin, SOT-23

Secondary-side synchronous rectification controllers from Fairchild Semiconductor for use in AC-DC flyback PWM converter applications.

Off-Line & Isolated DC-DC Controllers, Fairchild Semiconductor

The Flyback controllers, Line Level Control (LLC) controllers, and Primary-Side Regulation controllers offer Crucial energy savings to address the needs of Switch Mode Power Supply (SMPS) designs.
All controllers come with integrated soft-start, and protection features from over-voltage, open-feedback, overload, output-short, overcurrent, voltage brownout, and Undervoltage-Lockout.
