Feature Set and Extended Power Range Product Highlights Lower System Cost, Higher Design Flexibility - Multi-mode operation maximizes efficiency at all loads - New e SIP-7F and e SIP-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 e SIP-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 k Hz 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 + - D TOPSwitch-HX CONTROL C Figure 1. Typical Flyback Application. PI-4510-100206 - 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 Output Power...
