LNK304GN-TL is a LinkSwitch-TN family lowest component count, energy-efficient off-line switcher IC. It is specifically designed to replace all linear and capacitor-fed non-isolated power supplies in the under 360mA output current range at equal system cost while offering much higher performance and energy efficiency. It integrates a 700V 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. Start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias supply and associated circuitry in buck or flyback converter. The fully integrated auto-restart circuit in the safely limits output power during fault conditions such as short-circuit or open loop, reducing component count and system-level load protection cost. Application includes appliances and timers, LED drivers and industrial controls.
