Enhanced EcoSmart
, Integrated Off-Line Switcher with
Advanced Feature Set and Extended Power Range
Product Highlights
Lower System Cost, Higher Design Flexibility
Multi-mode operation maximizes effi ciency 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 heatsink 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 fi lter cost
