• Output overload protection (OPP)
• Vertical orientation for minimum PCB footprint
• Simple heat sink mounting using clip provides thermal
impedance equivalent to a TO-220
• Extended creepage to DRAIN pin
• Heat sink is connected to SOURCE for low EMI
• Output overvoltage protection (OVP)
• User programmable for hysteretic/latching shutdown
• Simple fast AC reset
• Primary or secondary sensed
• Line undervoltage (UV) detection prevents turn-off glitches
• Line overvoltage (OV) shutdown extends line surge withstand
• Accurate thermal shutdown with large hysteresis (OTP)
Description
TOPSwitch-JX cost effectively incorporates a 725 V power
MOSFET, high voltage switched current source, multi-mode
PWM control, oscillator, thermal shutdown circuit, fault
protection and other control circuitry onto a monolithic device.
Advanced Package Options
• eDIP™-12 package:
• Low profile horizontal orientation for ultra-slim designs
