Power Integrations (LNK305GN-TL) AC/DC Converter, Buck/Buck-Boost/Flyback,

AC/DC Converter, Buck/Buck-Boost/Flyback, 85 to 265 VAC In, SMD DIP-7 Product Overview 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 Product Information Input Voltage AC Min: 85V Input Voltage AC Max: 265V AC / DC Converter Case Style: SMD DIP No. of Pins: 7Pins Power Rating: 80mW Topology: Buck, Buck-Boost, Flyback Operating Temperature Min: -40°C Operating Temperature Max: 150°C Product Range: LinkSwitch-TN Series MSL: MSL 3 - 168 hours
