• 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  
PI-4510-100206  
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
