TOP257EN Product details

Description
TOPSwitch-HX cost effectively incorporates a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.

Product Highlights
Lower System Cost, Higher Design Flexibility
•  Multi-mode operation maximizes effciency 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 flter 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 feld reliability
