LNK353 Datasheet | Power Integrations

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 ponents - 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 ponent 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 pensation needed - No bias winding - simpler, lower cost transformer - High frequency switching - smaller and lower cost transformer - Very low ponent 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 Eco Smart - Extremely Energy Efficient - No-load consumption <300 m W without bias winding at 265 VAC input - Meets California Energy mission (CEC), Energy Star, and EU requirements Applications - Chargers for cell/cordless phones, PDAs, digital cameras, MP3/portable audio devices, shavers etc. - Standby and auxiliary supplies ® Enhanced, Energy Efficient, Low Power Off-Line Switcher IC + DC Output + Wide Range HV DC Input Link Switch-HF FB BP PI-3855-022704 Figure 1.
