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
