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
