TOP257LG-TL规格书详情
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 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 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
• 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
