Fully integrated auto-restart for short circuit and open loop fault protection
66 kHz operation with accurate current limit
Tight tolerances and negligible temperature variation
High breakdown voltage of 700 V
Frequency jittering dramatically reduces EMI (∼10 dB)
Built-in current limit and hysteretic thermal protection
High thermal shutdown temperature (+135 °C minimum)
Consumes typically only 50/80 mW in self-powered buck topology at 115/230 V ac input with no-load (opto feedback)
Consumes typically only 7/12 mW in flyback topology with external bias at 115/230 V ac input with no-load

Tight tolerances and negligible temperature variation
System level thermal overload, output short-circuit and open loop protection
Supports buck, buck-boost and flyback topologies
Excellent line and load regulation even with typical configuration
High bandwidth provides fast turn-on with no overshoot
Current limit operation rejects line ripple
Built-in current limit and hysteretic thermal protection
