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.
Product Highlights
EcoSmart® - Energy Effcient
• Energy effcient over entire load range
• No-load consumption below 100 mW at 265 VAC
• Up to 750 mW standby output power for 1 W input at 230 VAC

High Design Flexibility for Low System Cost
• Multi-mode PWM control maximizes effciency at all loads
• 132 kHz operation reduces transformer and power supply size
    • 66 kHz option for highest effciency requirements
• Accurate programmable current limit
• Optimized line feed-forward for line ripple rejection
• Frequency jittering reduces EMI flter cost
• Fully integrated soft-start for minimum startup stress
• 725 V rated MOSFET
    • Simplifes 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)
    • Output overload protection (OPP)
• 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)

Advanced Package Options
• eDIP™-12 package:
    • Low profle horizontal orientation for ultra-slim designs
