Lower System Cost, Higher Design Flexibility

? Multi-mode operation maximizes efficiency at all loads

? New eSIP-7F and eSIP-7C packages

? Low thermal impedance junction-to-case (2 °C per watt)

? 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
