Power Integrations LNK304PN Понижающий преобразователь

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
• Built-in current limit and hysteretic thermal protection
