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
