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
Figure 1.
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
