LNK305GN-TL

LinkSwitch™-TN is specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in under 360mA output current range at equal system cost while offering much higher performance and energy efficiency. LinkSwitch-TN devices integrate 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. The 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 converters. The fully integrated auto-restart circuit in the LNK304-306 safely limits output power during fault conditions such as short-circuit or open loop, reducing component count and system-level load protection cost. Applications include appliances, timers, LED drivers and industrial controls.

• Output current of 175mA (MDCM), 280mA (CCM) at 230VAC and 175mA (MDCM), 280mA (CCM) at 85-265VAC
• Cost effective linear/cap dropper replacement, EcoSmart™ extremely energy efficient
• Much higher performance over discrete buck and passive solutions
• Lowest cost and component count buck converter solution
• Fully integrated auto-restart for short-circuit and open loop fault protection
• Tight tolerances and negligible temperature variation
• Supports buck, buck-boost and flyback topologies
• Higher efficiency than passive solutions, Higher power factor than capacitor-fed solutions
• Consumes only 50/80mW in self-powered buck topology at 115/230VAC input with no-load (opto feedback)
• Meets California Energy Commission (CEC), Energy Star and EU requirements
