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 225mA (MDCM), 360mA (CCM) at 230VAC and 225mA (MDCM), 360mA (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
