• Optimized line feed-forward for line ripple rejection  
• Frequency jittering reduces EMI filter cost  
• Fully integrated soft-start for minimum startup stress  
• 725 V rated MOSFET  
PI-5578-090309  
Figure 1. Typical Flyback Application.  
• Simplifies meeting design derating requirements  
Extensive Protection Features  
• Auto-restart limits power delivery to <3% during overload faults  
• Output short-circuit protection (SCP)  
• Output over-current protection (OCP)  
• Heat transfer to both PCB and heat sink  
• Optional external heat sink provides thermal impedance  
equivalent to a TO-220  
• eSIP®-7C package:  
• 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
