Product Information
The STR-X6759N is a quasi-resonant topology IC designed for SMPS applications. It shows lower EMI noise characteristics than conventional PWM solutions, especially at greater than 2 MHz. It also provides a soft-switching mode to turn on the internal MOSFET at close to zero voltage (VDSbottom point) by use of the resonant characteristic of primary inductance and a resonant capacitor.
The package is a fully molded TO-3P, which contains the controller chip (MIC) and MOSFET, enabling output power up to 280 W at 120 VAC input. The bottom-skip
mode skips the first bottom of VDS and turns on the MOSFET at the second bottom point, to minimize an increase of operating frequency at light output load, improving systemlevel efficiency over the entire load range
