STR-W6765 - Quasi-Resonant Topology Primary Switching Reg.

Quasi-resonant topology IC ? Low EMI noise and soft switching Bottom-skip operation ? Improved system efficiency over the entire output load by avoiding increase of switching frequency Standby burst mode operation ? Lowers input power at very light output load condition Avalanche-guaranteed MOSFET ? Improves system-level reliability and does not require VDSS derating 800 V / 1.8 O, 52 to 110 W (Universal/230 Vac input) Various protections ? Improved system-level reliability Pulse-by-pulse drain overcurrent limiting Overvoltage protection (bias winding voltage sensing), with latch Overload protection with latch Maximum on-time limit
