Features Optimized for Lowest System Cost
• Fully integrated auto-restart for short-circuit and open
loop protection
• Self-biased supply – saves transformer auxiliary winding
and associated bias supply components
• Tight tolerances and negligible temperature variation on
key parameters eases design and lowers cost
• High maximum switching frequency allows very low
flux density transformer designs, practically eliminating
audible noise
• Frequency jittering greatly reduces EMI
• Packages with large creepage to high voltage pin
• Lowest component count switcher solution
Much Better Performance over Linear/RCC
• Lower system cost than RCC, discrete PWM and other
integrated solutions
• Universal input range allows worldwide operation
• Simple ON/OFF control – no loop compensation needed
• No bias winding – simpler, lower cost transformer
• High frequency switching – smaller and lower cost
transformer
• Very low component count – higher reliability and single
side printed circuit board
• High bandwidth provides fast turn on with no overshoot
and excellent transient load response
• Current limit operation rejects line frequency ripple
• Built-in current limit and hysteretic thermal shutdown
protection
EcoSmart®– Extremely Energy Efficient
• No-load consumption <300 mW without bias winding at
265 VAC input
• Meets California Energy Commission (CEC), Energy
Star, and EU requirements
