TOP264-271 TOPSwitch™-JX Family
Integrated Off-Line Switcher with EcoSmart™ Technology for Highly Efficient Power Supplies
Product Highlights
EcoSmart – Energy Efficient • Ideal for applications from 10 W to 245 W • Energy efficient 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 efficiency at all loads • 132 kHz operation reduces transformer and power supply size
• 66 kHz option for highest efficiency requirements • Accurate programmable current limit • Optimized line feed-forward for line ripple rejection • Frequency jittering reduces EMI filter cost • Fully integrated soft-start for minimum start-up stress • 725 V rated MOSFET
• 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) • 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:
• 43 W / 117 W universal input power output capability with PCB / metal heat sink
• Low profile horizontal orientation for ultra-slim designs • Heat transfer to both PCB and heat sink • Optional external heat sink provides thermal impedance
equivalent to a TO-220 • eSIP™-7C package:
• 177 W universal input output power capability • Vertical orientation for minimum PCB footprint • Simple heat sink mounting using clip provides thermal
impedance equivalent to a TO-220 • eSOP™-12 package:
• 66 W universal input output power capability • Low profile surface mounted for ultra-slim designs • Heat transfer to PCB via exposed pad and SOURCE pins • Supports wave or reflow soldering • Extended creepage to DRAIN pin • Heat sink is connected to SOURCE for low EMI
