LNK304 LinkSwitch-TN Buck Converter
The Power Integrations LNK304 LinkSwitch™-TN device family are Buck Converter ICs that provide a low component count step down solution. The LNK304 has been designed to offer a higher performing alternative when compared to linear and passive component solutions.
Applications
The LNK304 LinkSwitch buck convertor is ideal for use in appliances and timers, and for LED drivers and industrial controls.
Features
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

LinkSwitch-TN is specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at equal system cost while offering much higher performance and energy efficiency. LinkSwitch-TN devices integrate a 700 V power MOSFET, oscillator, simple On/Off control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry onto a monolithic IC.
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
