Features and Benefits
▪ 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 systemlevel reliability and does not require VDSS derating
▪ 800 V / 1.8 Ω, 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
