LinkSwitch-TN, Power Integrations
The LinkSwitch-TN family of very low power AC-DC, Non-Isolated passive power supply replacements.
700 V Internal MOSFET RatingSelf-PoweredON/OFF ControlHysteretic Thermal ShutdownPower LimitingFrequency Jitter Reduces EMIEcoSmart Low Standby/No-load Power Consumption
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 variationSystem level thermal overload, output short-circuit and open loop protectionSupports buck, buck-boost and flyback topologiesExcellent line and load regulation even with typical configurationHigh bandwidth provides fast turn-on with no overshootCurrent limit operation rejects line rippleBuilt-in current limit and hysteretic thermal protection
