?  Low height is ideal for adapters where space is limited
?  Simple mounting using a clip to aid low cost manufacturing
?  Horizontal eSIP-7F package ideal for ultra low height adapter
and monitor applications
?  Extended package creepage distance from DRAIN pin to
adjacent pin and to heat sink

?  No heat sink required up to 35 W using P, G and M packages
with universal input voltage and up to 48 W at 230 VAC
?  Output overvoltage protection (OVP) is user programmable for
latching/non-latching shutdown with fast AC reset

?  Allows both primary and secondary sensing
?  Line undervoltage (UV) detection prevents turn-off glitches
?  Line overvoltage (OV) shutdown extends line surge limit
?  Accurate programmable current limit
?  Optimized line feed-forward for line ripple rejection
?  132 kHz frequency (254Y-258Y and all E/L packages) reduces
transformer and power supply size
?  Half frequency option for video applications
?  Frequency jittering reduces EMI filter cost

Heat sink is connected to SOURCE for low EMI
Improved auto-restart delivers <3% of maximum power in
short circuit and open loop fault conditions
Accurate hysteretic thermal shutdown function automatically
recovers without requiring a reset
Fully integrated soft-start for minimum start-up stress
Extended creepage between DRAIN and all other pins
improves field reliability
