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
