®
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 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 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 filter cost

Typical Flyback Application.
Heatsink 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
