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
output load condition
▪ Avalanche-guaranteed MOSFET  Improves system-level
reliability and does not require VDSS derating
▪ 800 VDSS / 0.66 Ω RDS(on)
▪ 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
