Description: The STR-W6754 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 (VDS bottom point) by use of the resonant characteristic of primary inductance and a resonant capacitor.
Features and Benefits: Quasi-resonant topology IC ---Low EMI noise and soft switching Bottom-skip mode ---Improved system efficiency over the entire output load by avoiding increase of switching frequency Auto-Standby mode ---Lowers input power at very light utput load condition Avalanche-guaranteed MOSFET ---Improves system-level reliability and does not require VDSS derating 650 V / 0.96 Various protections ---Improved system-level reliability
